From the Congressional Quarterly:
Former New York City Mayor Rudolph Giuliani has led the long list of 2008 Republican presidential contenders in early preference polls — and his perceived position as the front-runner, at least for now, was not contradicted by his recent campaign finance report, which shows he has already built a sizable treasury.
Giuliani’s campaign reported total first-quarter receipts of $16.6 million, which included a $1.85 million transfer from the presidential “exploratory” committee he established last November.
With total receipts of $18 million for his campaign to date, Giuliani leads all but three of the current crop of White House hopefuls — Democratic Sens. Hillary Rodham Clinton of New York and Barack Obama of Illinois, and Republican Mitt Romney, the former Massachusetts governor — in overall campaign receipts.
