In the OTL, Al Gore was one of the media favorites for who could run for the presidency in 2008. He would have been in a similar position as Nixon 40 years previous; a man who lost the election by a very close margin, who had gone out into the political wilderness, and 8 years later was in a world where the current administration had made unpopular decisions and America was in an unpopular war. Al Gore did not run, and the contest was heated between Clinton, Edwards and Obama before Obama won the nomination and the presidency.
What if Al Gore had decided to pursue the Democratic nomination for president? What would that contest look like, what is the likelihood of him securing the nomination, who would he pick for VP, what would the election look like between him and the Republican nominee, and what would a Gore administration look like and a President Gore America look like?
