Republican Party nomination
For both Republicans and Democrats, there were movements of support for General Dwight D. Eisenhower, the most popular general of World War II and a favorite in the polls. Unlike the latter movement within the Democratic Party, however, the Republican draft movement came largely from the grassroots of the party. By January 23, 1948, the grassroots movement had successfully entered Eisenhower's name into every state holding a Republican presidential primary, and polls gave him a significant lead against all other contenders. With the first state primary approaching, Eisenhower was forced to make a quick decision. Stating that soldiers should keep out of politics, Eisenhower declined to run and requested that the grassroots draft movement cease its activities. After a number of failed efforts to get Eisenhower to reconsider, the organization disbanded, with the majority of its leadership endorsing the presidential campaign of the former Governor of Minnesota, Harold Stassen. With Eisenhower refusing to run, the contest for the Republican nomination was between Stassen, New York Governor Thomas E. Dewey, Senator Robert A. Taft from Ohio, California Governor Earl Warren, General Douglas MacArthur, and Senator Arthur H. Vandenberg from Michigan, the senior Republican in the Senate. Dewey, who had been the Republican nominee in 1944, was regarded as the frontrunner when the primaries began. Dewey was the acknowledged leader of the Republican Party's Eastern Establishment. In 1946 he had been re-elected governor of New York by the largest margin in state history. Dewey's handicap was that many Republicans disliked him on a personal level; he often struck observers as cold, stiff, and calculating. Taft was the leader of the Republican Party's conservative wing, which was strongest in the Midwest and parts of the South. Taft called for abolishing many New Deal welfare programs, which he felt were harmful to business interests, and he was skeptical of American involvement in foreign alliances such as the United Nations. Taft had two major weaknesses: He was a plodding, dull campaigner, and he was viewed by most party leaders as being too conservative and controversial to win a presidential election.Both Vandenberg and Warren were highly popular in their home states, but each refused to campaign in the primaries, which limited their chances of winning the nomination. Their supporters, however, hoped that in the event of a Dewey-Taft-Stassen deadlock, the convention would turn to their man as a compromise candidate. General MacArthur, the famous war hero, was especially popular among conservatives. Since he was serving in Japan as the Supreme Commander of the Allied Powers occupying that nation, he was unable to campaign for the nomination. He did make it known, however, that he would accept the GOP nomination if it were offered to him, and some conservative Republicans hoped that by winning a primary contest he could prove his popularity with voters. They chose to enter his name in the Wisconsin primary. His candidacy was enthusiastically supported by William Randolph Hearst in all of his newspapers.  
The "surprise" candidate of 1948 was Stassen, a liberal from Minnesota. In 1938, Stassen had been elected governor of Minnesota at the age of 31; he resigned as governor in 1943 to serve in the wartime Navy. In 1945 he served on the committee that created the United Nations. Stassen was widely regarded as the most liberal of the Republican candidates, yet during the primaries he was criticized for being vague on many issues. Stassen stunned Dewey and MacArthur in the Wisconsin primary; Stassen's surprise victory virtually eliminated General MacArthur, whose supporters had made a major effort on his behalf. Stassen defeated Dewey again in the Nebraska primary, thus making him the new frontrunner. He then made the strategic mistake of trying to beat Taft in Ohio, Taft's home state. Stassen believed that if he could defeat Taft in his home state, Taft would be forced to quit the race and most of Taft's delegates would support him instead of Dewey. Taft defeated Stassen in his native Ohio, and Stassen earned the hostility of the party's conservatives. Even so, Stassen was still leading Dewey in the polls for the upcoming Oregon primary. Dewey, however, realized that losing another primary would end his chances at the nomination, and he decided to make an all-out effort in Oregon.In April 1948, Dewey sent Paul Lockwood, one of his top aides, to build a strong grassroots organization in the state. Working with $150,000 sent by Dewey's powerful New York political organization (three times the previous record spent in an Oregon primary), Lockwood paid "for 126 billboards, hundreds of sixty-second radio spots on every station in the state, and half-hour broadcasts each noon...The daily Portland Oregonian carried five Dewey advertisements a day." Dewey also extensively campaigned in Oregon, spending three weeks in the state. He "invaded every hamlet, no matter how isolated, speaking at rural crossroads and shaking hands in hamburger stands. One journalist commented that Dewey was the greatest explorer of Oregon since Lewis and Clark."Dewey also agreed to debate Stassen in Oregon on national radio. Held on May 17, 1948, it was the first-ever radio debate between presidential candidates. The sole issue of the debate concerned whether to outlaw the Communist Party of the United States. Stassen, despite his liberal reputation, argued in favor of outlawing the party, stating his belief that a network of Soviet-directed Communist spies "within the U.S. demanded immediate, and punitive, response...Why did Dewey oppose such a ban? Stassen wanted to know." "We must not coddle Communism with legality", Stassen insisted. Dewey - while criticizing Communist totalitarianism and Soviet actions in the Cold War - still forcefully argued against banning the Communist Party: "This outlawing idea is nothing new...for thousands of years despots have tortured, imprisoned, killed, and exiled their opponents, and their governments have always fallen into the dust." Dewey ended his turn in the debate by stating that "I am unalterably, wholeheartedly, and unswervingly against any scheme to write laws outlawing people because of their religious, political, social, or economic ideas. I am against it because it is a violation of the Constitution of the United States and the Bill of Rights...I am against it because I know from a great many years of experience in law enforcement that the proposal wouldn't work. Stripped to its naked essentials...this is nothing but the method of Hitler and Stalin. It is thought control...an attempt to beat down ideas with a club. It is a surrender of everything we believe in." Surveys showed that from 40 to 80 million people nationwide listened to the debate, and most observers rated Dewey as the winner. Four days after the debate, Dewey defeated Stassen in the Oregon primary. From this point forward, the New York governor had the momentum he needed to win his party's nomination for a second straight time.
