With the 1992 Democratic primary approaching, four candidates threw their hat in the ring. In pole position in early polling was Massachusetts Senator Paul Tsongas. He was popular and well respected, but many Democrats remembered what had happened the last time they'd made an uncharismatic Greek-American from Massachusetts their nominee.
Also in the pack was Iowa Senator Tom Harkin. Harkin, a populist in the New Deal style, hoped to win voters from the left of the Democratic Party. However, he faced a major obstacle to that path to victory.
Jerry Brown, governor of California and darling of many progressives, had also entered the race, with an eclectic mix of Democratic and Republican policies (such as a flat tax).
The final candidate that year was Bob Kerrey, Vietnam veteran and former governor of and current Senator from Nebraska.
The first debate was considered something of a mess for the candidates. Harkin, hoping to win over progressives, viciously went after Jerry Brown's conservative tax plan, calling Brown "A Hippie Republican." Brown responded by calling Harkin "obsolete". Tsongas was competent, but unspectacular, inspiring yet more Dukakis comparisons. Kerrey was the only candidate to escape unscathed.
