1948: Franklin Roosevelt has died in office. The United States has risen out of the Great Depression and WWII. Harry Truman succeeded Roosevelt as president. The PDNC of 48 was disasterous. The Conservative wing of the Progressive Democrats, lead by Strom Thurmond, was increasingly angry about being outnumbered within their own party. The Civil Rights movement was gaining support within the party, which caused more protest by the Conservative wing of the PD. Many Southern Progressive Democrats walked out of the convention in anger. These politicians split off from the Progressive Democrats to reform the Democratic Party, the remaining Progressive Democrats to be called the Progressives. The Progressives that remained were nearly unanimous in reelecting Truman. Meanwhile the Republican Party was anxious to return to power, and re-nominated Thomas Dewey as the nominee. Truman defeated both Dewey, and the Democratic nominee, Strom Thurmond.

1952- The first Progressive President, Harry Truman, has declined to run for a second term. Foreign relations were tense around the world, due to the Cold War, the Korean War, and the communist revolution in China. A recession made the Progressive party unpopular, so they nominated Adlai Stevenson of Illinois, a talented orator. Dwight Eisenhower, a famous WWII general, won the Republican nomination. The democrats also re-nomianted Strom Thurmond. In a record close race, Eisenhower narrowly won the popular and electoral vote, while the democrats were unsuccessful, as the Progressives were successful in the south. Results:

1956- In a rare occurence, the three major parties, the Republicans, Progressives, and Democrats renominated the same candidates, President Dwight Eisenhower, Adlai Stevenson, and Strom Thurmond respectively. After an end to the Korean War and a prospering economy, Eisenhower was immensely popular. Stevenson, who was one of the most moderate members of the Progressives, swept the deep south by avoiding Civil Rights. Eisenhower alos avoided it, and only Thurmond opposed it. After a landslide victory for Eisenhower, both the Progressives and the Democrats faced disappointment. After the two time defeat of Stevenson, the Progressives lacked a leader. And Strom Thurmond once again had not won a single state, leading members of the Democrats to speculate with joining another party.

So I think the first election this is going to change will be 1968 - it's the first close election the Republican won, no?

[PJ]

Yeah. There will be a lot of different results from 68 onward.

1960- The economic recession of the time had made the republican party unpopular, leading the progressives and Democrats to hope for a victory. John F kennedy was nominated by the Progressive Party, and Harry Byrd was nominated by the democrats. Despite the fact that the democrats had nominated someone new for the first time since 1948, Byrd was only leading in polls in MS. He approached the Republican candidate, Richard Nixon, to discuss a potential alliance, a controversial topic within the party which Byrd's VP, Strom Thurmond, opposed. Nixon had not yet selected a VP. On August 1960, Nixon shocked America when he announced that he would leave the Republican Party to work with Byrd on creating a new party, which would according to Nixon, "unite Americans of similar and opposing viewpoints for a greater tomorrow. This party will be named after the great party founded by the founding fathers, the Democratic Republican Party." The party held no public office, but nominated Nixon as President and Byrd as VP for the 1960 election. The republican party was divided on the issue, as some supported Nixon and decided to run under the Democratic Republicans, while others ran under the Republican party. The remaining republican party did not have time to nominate another candidate, and reluctantly endorsed Nixon. Nixon had poor campaign strategies however, and hoped Byrd being on the ticket would help him carry the deep south, while it only helped him carry MS.

1964: After the assasination of extremely popular president John F Kennedy, Lyndon Johnson was sworn in as President. In the election of 64, Johnson successfully associated himself with Kennedy's popularity, which was higher than the actual results of 1960's election for nearly all of Kennedy's term. Johnson further campaigned for Civil Rights, which was initially supported by Kennedy. Meanwhile, the Democratic Republican party was eager to hold presidential office for the first time, and nominated Barry Goldwater. However, the Republican Party still existed, and Nelson Rockefeller was currently the leader of the party, which mainly consisted of moderate conservatives, and held very few seats in congress. They were outnumbered by Progressives and Democratic Republicans alike. At The Republican Convention, Rockefeller surprised America when he announced, that knowing he couldn't win, he would leave the race before the election. Not only that, but he announced his support for Johnson instead of Goldwater. Goldwater's opposition to Civil Rights made him extremely unpopular. On election night, Johnson won a whopping 66% of the popular vote. Results:

1968- Lyndon Johnson decided not to run for a 2nd term. Civil Rights was becoming an increasingly controversial issue, partly due to the assasination of Martin Luther King jr. The Progressives nominated Hubert Humphrey, who strongly supported Civil Rights. For the first time since 1956, the Republicans nominated a candidate, George Romney. The Democratic Republicans strongly opposed Civil Rights, and nominated segregationist George Wallace. Due to the increasing popularity of the Civil Rights Movement, Humphrey defeated Romney and Wallace for the Presidency.
