In February 1983, during his second term, Hart announced his candidacy for president in the 1984 presidential election. At the time of his announcement, Hart was a little-known senator and barely received above 1 percent in the polls against better-known candidates such as Walter Mondale, John Glenn and Jesse Jackson. To counter this situation, Hart started campaigning early in New Hampshire, making a then-unprecedented canvassing tour in late September, months before the primary. This strategy attracted national media attention to his campaign, and by late 1983, he had risen moderately in the polls to the middle of the field, mostly at the expense of the sinking candidacies of Glenn and Alan Cranston. Mondale won the Iowa caucus in late January, but Hart polled a respectable 16 percent. Two weeks later, in the New Hampshire primary, he shocked much of the party establishment and the media by defeating Mondale by 10 percentage points. Hart instantly became the main challenger to Mondale for the nomination and appeared to have the momentum on his side.
