Primaries
After Hart withdrew from the race, no clear frontrunner emerged before the primaries and caucuses began. The Iowa caucus was won by Dick Gephardt, who had been sagging heavily in the polls until, three weeks before the vote, he began campaigning as a populist and his numbers surged. Illinois Senator Paul M. Simon finished a surprising second, and Massachusetts Governor Michael Dukakis finished third. In the New Hampshire primary, Dukakis came in first place, Gephardt fell to second, and Simon came in third. In an effort to weaken Gephardt's candidacy, both Dukakis and Tennessee Senator Al Gore ran negative television ads against Gephardt. The ads convinced the United Auto Workers, which had endorsed Gephardt, to withdraw their endorsement; this crippled Gephardt, as he relied heavily on the support of labor unions.
In the Super Tuesday races, Dukakis won six primaries, to Gore's five, Jesse Jackson five and Gephardt one, with Gore and Jackson splitting the Southern states. The next week, Simon won Illinois with Jesse Jackson finishing second. 1988 remains the race with the most candidates winning primaries since the McGovern reforms of 1971. Jackson captured 6.9 million votes and won 11 contests: seven primaries (Alabama, the District of Columbia, Georgia, Louisiana, Mississippi, Puerto Rico and Virginia) and four caucuses (Delaware, Michigan, South Carolina and Vermont). Jackson also scored March victories in Alaska's caucuses and Texas's local conventions, despite losing the Texas primary. Briefly, after he won 55% of the vote in the Michigan Democratic caucus he had more pledged delegates than all the other candidates.
However, Jackson's campaign suffered a significant setback less than two weeks later when he was defeated handily in the Wisconsin primary by Michael Dukakis. Dukakis's win in New York and then in Pennsylvania effectively ended Jackson's hopes for the nomination.
