Clinton has drawn parallels between 2000 and 2016. During a February Democratic town hall, Clinton mentioned her 2000 race and said “people were barraging,” citing Giuliani by name.

Given his more moderate record, Clinton focused instead on Giuliani’s temperament and cast him as too combative. She also sought to paint him as a xenophobe by playing up appearance on the same state as far-right Austrian leader Joerg Haider. And she focused on minority outreach, including visiting a number of black churches.

USA TODAY reached out to Giuliani, but his office said the former mayor was unavailable for comment.
