Question: What is the nickname of the state where John Kerry's VP pick was a senator?

full_context: Document 1: 2004 United States presidential election: The following week, John Edwards won the South Carolina primary and finished a strong second in Oklahoma to Clark. Lieberman dropped out of the campaign the following day. Kerry dominated throughout February and his support quickly snowballed as he won caucuses and primaries, taking in a string of wins in Michigan, Washington, Maine, Tennessee, Washington, D.C., Nevada, Wisconsin, Utah, Hawaii, and Idaho. Clark and Dean dropped out during this time, leaving Edwards as the only real threat to Kerry. Kucinich and Sharpton continued to run despite poor results at the polls.
Document 2: North Carolina: As in the rest of the former Confederacy, North Carolina had become a one-party state, dominated by the Democratic Party. Impoverished by the Civil War, the state continued with an economy based on tobacco, cotton and agriculture. Towns and cities remained few in the east. A major industrial base emerged in the late 19th century in the western counties of the Piedmont, based on cotton mills established at the fall line. Railroads were built to connect the new industrializing cities. The state was the site of the first successful controlled, powered and sustained heavier-than-air flight, by the Wright brothers, near Kitty Hawk on December 17, 1903. In the first half of the 20th century, many African Americans left the state to go North for better opportunities, in the Great Migration. Their departure changed the demographic characteristics of many areas.
Document 3: North Carolina: According to a Forbes article written in 2013 Employment in the "Old North State" has gained many different industry sectors. See the following article summary: science, technology, energy and math, or STEM, industries in the area surrounding North Carolina's capital have grown 17.9 percent since 2001, placing Raleigh-Cary at No. 5 among the 51 largest metro areas in the country where technology is booming. In 2010 North Carolina's total gross state product was $424.9 billion, while the state debt in November 2012, according to one source, totalled US$2.4bn, while according to another, was in 2012 US$57.8bn. In 2011 the civilian labor force was at around 4.5 million with employment near 4.1 million. The working population is employed across the major employment sectors. The economy of North Carolina covers 15 metropolitan areas. In 2010, North Carolina was chosen as the third-best state for business by Forbes Magazine, and the second-best state by Chief Executive Officer Magazine.
Document 4: 2004 United States presidential election: On March 10, 2004, Bush officially clinched the number of delegates needed to be nominated at the 2004 Republican National Convention in New York City. Bush accepted the nomination on September 2, 2004, and selected Vice President Dick Cheney as his running mate. (In New York, the ticket was also on the ballot as candidates of the Conservative Party of New York State.) During the convention and throughout the campaign, Bush focused on two themes: defending America against terrorism and building an ownership society. The ownership society included allowing people to invest some of their Social Security in the stock market, increasing home and stock ownership, and encouraging more people to buy their own health insurance.
Document 5: 2004 United States presidential election: By the January 2004 Iowa caucuses, the field had dwindled down to nine candidates, as Bob Graham had dropped out of the race. Howard Dean was a strong front-runner. However, the Iowa caucuses yielded unexpectedly strong results for Democratic candidates John Kerry, who earned 38% of the state's delegates and John Edwards, who took 32%. Former front-runner Howard Dean slipped to 18% and third place, and Richard Gephardt finished fourth (11%). In the days leading up to the Iowa vote, there was much negative campaigning between the Dean and Gephardt camps.
Document 6: John Kerry: During his bid to be elected president in 2004, Kerry frequently criticized President George W. Bush for the Iraq War. While Kerry had initially voted in support of authorizing President Bush to use force in dealing with Saddam Hussein, he voted against an $87 billion supplemental appropriations bill to pay for the subsequent war. His statement on March 16, 2004, "I actually did vote for the $87 billion before I voted against it," helped the Bush campaign to paint him as a flip-flopper and has been cited as contributing to Kerry's defeat.

Document 8: 2004 United States presidential election: In sheer numbers, Kerry had fewer endorsements than Howard Dean, who was far ahead in the superdelegate race going into the Iowa caucuses in January 2004, although Kerry led the endorsement race in Iowa, New Hampshire, Arizona, South Carolina, New Mexico and Nevada. Kerry's main perceived weakness was in his neighboring state of New Hampshire and nearly all national polls. Most other states did not have updated polling numbers to give an accurate placing for the Kerry campaign before Iowa. Heading into the primaries, Kerry's campaign was largely seen as in trouble, particularly after he fired campaign manager Jim Jordan. The key factors enabling it to survive were when fellow Massachusetts Senator Ted Kennedy assigned Mary Beth Cahill to be the campaign manager, as well as Kerry's mortgaging his own home to lend the money to his campaign (while his wife was a billionaire, campaign finance rules prohibited using one's personal fortune). He also brought on the "magical" Michael Whouley who would be credited with helping bring home the Iowa victory the same as he did in New Hampshire for Al Gore in 2000 against Bill Bradley.
Document 9: 2004 United States presidential election: In March's Super Tuesday, Kerry won decisive victories in the California, Connecticut, Georgia, Maryland, Massachusetts, New York, Ohio, and Rhode Island primaries and the Minnesota caucuses. Dean, despite having withdrawn from the race two weeks earlier, won his home state of Vermont. Edwards finished only slightly behind Kerry in Georgia, but, failing to win a single state other than South Carolina, chose to withdraw from the presidential race. Sharpton followed suit a couple weeks later. Kuninch did not leave the race officially until July.
Document 10: St. John's, Newfoundland and Labrador: The economy has been growing quickly in recent years. In both 2010 and 2011, the metro area's gross domestic product (GDP) led 27 other metropolitan areas in the country, according to the Conference Board of Canada, recording growth of 6.6 per cent and 5.8 per cent respectively. At $52,000 the city's per capita GDP is the second highest out of all major Canadian cities. Economic forecasts suggest that the city will continue its strong economic growth in the coming years not only in the "oceanic" industries mentioned above, but also in tourism and new home construction as the population continues to grow. In May 2011, the city's unemployment rate fell to 5.6 per cent, the second lowest unemployment rate for a major city in Canada.
Document 11: 2004 United States presidential election: In September 2003, retired four-star general Wesley Clark announced his intention to run in the presidential primary election for the Democratic Party nomination. His campaign focused on themes of leadership and patriotism; early campaign ads relied heavily on biography. His late start left him with relatively few detailed policy proposals. This weakness was apparent in his first few debates, although he soon presented a range of position papers, including a major tax-relief plan. Nevertheless, the Democrats did not flock to support his campaign.
Document 12: 2004 United States presidential election: On July 6, John Kerry selected John Edwards as his running mate, shortly before the 2004 Democratic National Convention in Boston, held later that month. Days before Kerry announced Edwards as his running mate, Kerry gave a short list of three candidates: Sen John Edwards, Rep Dick Gephardt, and Gov Tom Vilsack. Heading into the convention, the Kerry/Edwards ticket unveiled their new slogan—a promise to make America "stronger at home and more respected in the world." Kerry made his Vietnam War experience the prominent theme of the convention. In accepting the nomination, he began his speech with, "I'm John Kerry and I'm reporting for duty." He later delivered what may have been the speech's most memorable line when he said, "the future doesn't belong to fear, it belongs to freedom", a quote that later appeared in a Kerry/Edwards television advertisement.
Document 13: John Kerry: In the 2004 Democratic presidential primaries, John Kerry defeated several Democratic rivals, including Sen. John Edwards (D-North Carolina.), former Vermont Governor Howard Dean and retired Army General Wesley Clark. His victory in the Iowa caucuses is widely believed to be the tipping point where Kerry revived his sagging campaign in New Hampshire and the February 3, 2004, primary states like Arizona, South Carolina and New Mexico. Kerry then went on to win landslide victories in Nevada and Wisconsin. Kerry thus won the Democratic nomination to run for President of the United States against incumbent George W. Bush. On July 6, 2004, he announced his selection of John Edwards as his running mate. Democratic strategist Bob Shrum, who was Kerry's 2004 campaign adviser, wrote an article in Time magazine claiming that after the election, Kerry had said that he wished he'd never picked Edwards, and that the two have since stopped speaking to each other. In a subsequent appearance on ABC's This Week, Kerry refused to respond to Shrum's allegation, calling it a "ridiculous waste of time."
Document 14: Raleigh, North Carolina: Raleigh's industrial base includes banking/financial services; electrical, medical, electronic and telecommunications equipment; clothing and apparel; food processing; paper products; and pharmaceuticals. Raleigh is part of North Carolina's Research Triangle, one of the country's largest and most successful research parks, and a major center in the United States for high-tech and biotech research, as well as advanced textile development. The city is a major retail shipping point for eastern North Carolina and a wholesale distributing point for the grocery industry.
Document 15: 2004 United States presidential election: Bush focused his campaign on national security, presenting himself as a decisive leader and contrasted Kerry as a "flip-flopper." This strategy was designed to convey to American voters the idea that Bush could be trusted to be tough on terrorism while Kerry would be "uncertain in the face of danger." Bush (just as his father did with Dukakis in the 1988 election) also sought to portray Kerry as a "Massachusetts liberal" who was out of touch with mainstream Americans. One of Kerry's slogans was "Stronger at home, respected in the world." This advanced the suggestion that Kerry would pay more attention to domestic concerns; it also encapsulated Kerry's contention that Bush had alienated American allies by his foreign policy.
