Question: Who is the spouse of the last Democratic presidential candidate to win any counties in Oklahoma?

full_context: Document 1: Politics of Texas: From 1848 until Richard M. Nixon's victory in 1972, Texas voted for the Democratic candidate for president in every election except 1928, when it did not support Catholic Al Smith. The state had a white majority and Democrats re-established their dominance after the Civil War. In the mid-20th century 1952 and 1956 elections, the state voters joined the landslide for Dwight D. Eisenhower. (Texas did not vote in 1864 and 1868 due to the Civil War and Reconstruction).
Document 2: Montana: In presidential elections, Montana was long classified as a swing state, though the state has voted for the Republican candidate in all but two elections from 1952 to the present. The state last supported a Democrat for president in 1992, when Bill Clinton won a plurality victory. Overall, since 1889 the state has voted for Democratic governors 60 percent of the time and Democratic presidents 40 percent of the time, with these numbers being 40/60 for Republican candidates. In the 2008 presidential election, Montana was considered a swing state and was ultimately won by Republican John McCain, albeit by a narrow margin of two percent.
Document 3: Tennessee: By 1960 African Americans comprised 16.45% of the state's population. It was not until after the mid-1960s and passage of the Voting Rights Act of 1965 that they were able to vote in full again, but new devices, such as at-large commission city governments, had been adopted in several jurisdictions to limit their political participation. Former Gov. Winfield Dunn and former U.S. Sen. Bill Brock wins in 1970 helped make the Republican Party competitive among whites for the statewide victory. Tennessee has selected governors from different parties since 1970. Increasingly the Republican Party has become the party of white conservatives.
Document 4: Northwestern University: Many students are involved in community service in one form or another. Annual events include Dance Marathon, a thirty-hour event that raised more than a million dollars for charity in 2011; and Project Pumpkin, a Halloween celebration hosted by the Northwestern Community Development Corps (NCDC) to which more than 800 local children are invited for an afternoon of games and sweets. NCDC's work is to connect hundreds of student volunteers to some twenty volunteer sites in Evanston and Chicago throughout the year. Many students have assisted with the Special Olympics and have taken alternative spring break trips to hundreds of service sites across the United States. Northwestern students also participate in the Freshman Urban Program, a program for students interested in community service. A large and growing number of students participate in the university's Global Engagement Summer Institute (GESI), a group service-learning expedition in Asia, Africa, or Latin America, in conjunction with the Foundation for Sustainable Development. Several internationally recognized non-profit organizations have originated at Northwestern including the World Health Imaging, Informatics and Telemedicine Alliance, a spin-off from an engineering student's honors thesis.
Document 5: Family Re-Union: Family Re-Union is an annual conference, hosted by former Vice President of the United States Al Gore and Tipper Gore, in Nashville, Tennessee whose goal is to bring together families and those who work with them to talk and design better ways to strengthen family life in America. At the center of Family Re-Union is the belief that programs and guidelines should respond to the needs of families and communities, and should build on their strengths.
Document 6: North Carolina: North Carolina's party loyalties have undergone a series of important shifts in the last few years: While the 2010 midterms saw Tar Heel voters elect a bicameral Republican majority legislature for the first time in over a century, North Carolina has also become a Southern swing state in presidential races. Since Southern Democrat Jimmy Carter's comfortable victory in the state in 1976, the state had consistently leaned Republican in presidential elections until Democrat Barack Obama narrowly won the state in 2008. In the 1990s, Democrat Bill Clinton came within a point of winning the state in 1992 and also only narrowly lost the state in 1996. In the early 2000s, Republican George W. Bush easily won the state by over 12 points, but by 2008, demographic shifts, population growth, and increased liberalization in heavily populated areas such as the Research Triangle, Charlotte, Greensboro, Winston-Salem, Fayetteville, and Asheville, propelled Barack Obama to victory in North Carolina, the first Democrat to win the state since 1976. In 2012, North Carolina was again considered a competitive swing state, with the Democrats even holding their 2012 Democratic National Convention in Charlotte. However, Republican Mitt Romney ultimately eked out a 2-point win in North Carolina, the only 2012 swing state that Obama lost, and one of only two states (along with Indiana) to flip from Obama in 2008 to the GOP in 2012.
Document 7: 2016 United States presidential election in Ohio: Ohio was won by Donald Trump by a margin of 8.1 points. Prior to the election, most news organizations considered the Buckeye State as leaning Republican, due to his appeal to blue collar voters in the rust belt. Ohio kept its streak of voting for the winner (a bellwether state) since 1964, as it voted for Trump, who won nationally. Having voted Democratic in 2012 and 2008, the win margin was the second largest of the states Trump flipped Red (after Iowa). It is also the largest victory margin since George H.W. Bush defeated Michael Dukakis in 1988. Ohio was an unprecedented 10 points more Republican - leaning than the nation in 2016.
Document 8: Philadelphia: From the American Civil War until the mid-20th century, Philadelphia was a bastion of the Republican Party, which arose from the staunch pro-Northern views of Philadelphia residents during and after the war (Philadelphia was chosen as the host city for the first Republican National Convention in 1856). After the Great Depression, Democratic registrations increased, but the city was not carried by Democrat Franklin D. Roosevelt in his landslide victory of 1932 (in which Pennsylvania was one of the few states won by Republican Herbert Hoover). Four years later, however, voter turnout surged and the city finally flipped to the Democrats. Roosevelt carried Philadelphia with over 60% of the vote in 1936. The city has remained loyally Democratic in every presidential election since. It is now one of the most Democratic in the country; in 2008, Democrat Barack Obama drew 83% of the city's vote. Obama's win was even greater in 2012, capturing 85% of the vote.
Document 9: Pauline LaFon Gore: Pauline LaFon Gore (October 6, 1912 – December 15, 2004) was the mother of former United States Vice President Al Gore and the wife of former United States Senator Al Gore Sr.. She is credited with playing a significant role in both of their careers with Al Gore saying "there will never be a better campaigner than Pauline LaFon Gore". Her advice was an important factor in his refusal to sign the "Southern Manifesto" opposing desegregation and his opposition to the Vietnam War which were critical issues in his bid for re-election as a Senator in 1970. She came from a poor family in small business to become one of the first female lawyers to graduate from Vanderbilt University and managed a Washington law firm in the 1970s.
Document 10: Politics of Texas: In a reversal of alignments, since the late 1960s the Republican Party has grown more prominent within the state based on an influx of primarily white voters (the majority in the state) from the Democratic Party. By the mid-1990s, it became the state's dominant political party.
Document 11: Tennessee: In the 2000 presidential election, Vice President Al Gore, a former Democratic U.S. Senator from Tennessee, failed to carry his home state, an unusual occurrence but indicative of strengthening Republican support. Republican George W. Bush received increased support in 2004, with his margin of victory in the state increasing from 4% in 2000 to 14% in 2004. Democratic presidential nominees from Southern states (such as Lyndon B. Johnson, Jimmy Carter, Bill Clinton) usually fare better than their Northern counterparts do in Tennessee, especially among split-ticket voters outside the metropolitan areas.
Document 12: Caribbean and Central America Action: Among the public figures speaking at the 33rd conference, held in 2009 in Miami, were the Prime Minister of Haiti, Jean-Max Bellerive, Canada's Minister of State of Foreign Affairs, Peter Kent and Puerto Rico's Secretary of State, Kenneth McClintock. The organization's policy-oriented programs have focused on tourism, financial services, policy and regulatory environments for business in the Americas, energy security, maritime port security, disaster mitigation, customs, telecommunications, intellectual property rights, information technology, agriculture and telecommunications. Cabinet-level officials have represented the United States at prior conferences.
Document 13: Knowbility: In 1999, in addition to hosting another AIR-Austin, Knowbility staff and volunteers developed an Accessible Web Page Design Curriculum that was freely distributed on its web site. By 2000, Knowbility had achieved a national profile: Knowbility was mentioned on an episode of The Oprah Winfrey Show in 2000 dealing with technology issues. On September 21, 2000, the White House issued a press release to highlight programs across the country helping to bridge the digital divide for people with disabilities; the Rocky Mountain AIR program was mentioned by President Bill Clinton as a noteworthy initiative. AIR was one of three programs selected for recognition by the Drucker Foundation in October 2000. That same year, Knowbility received an awarded for Notable Achievement in the public service category of the Texas Interactive Media Awards. Also in 2000, Knowbility Board Chair Steve Guengerich and intern Josh Blakeley were featured guests of a panel discussion in Washington DC. at a National Labor Summit, where AIR activities were highlighted as a "best practice" in contributing to the employment of people with disabilities.
Document 14: Oklahoma: After the 1948 election, the state turned firmly Republican. Although registered Republicans were a minority in the state until 2015, starting in 1952, Oklahoma has been carried by Republican presidential candidates in all but one election (1964). This is not to say that every election has been a landslide for Republicans: Jimmy Carter lost the state by less than 1.5% in 1976, while Michael Dukakis and Bill Clinton both won 40% or more of the state's popular vote in 1988 and 1996 respectively. Al Gore in 2000, though, was the last Democrat to even win any counties in the state. Oklahoma was the only state where Barack Obama failed to carry any of its counties in both 2008 and 2012.
Document 15: It Takes a Village: It Takes a Village: And Other Lessons Children Teach Us is a book published in 1996 by First Lady of the United States Hillary Rodham Clinton. In it, Clinton presents her vision for the children of America. She focuses on the impact individuals and groups outside the family have, for better or worse, on a child's well - being, and advocates a society which meets all of a child's needs.
