According to a poll from Fox News:

By 67 percent to 22 percent, American voters think the Democrats are going to win the 2008 presidential election. Fully 90 percent of Democrats think their party is going to be victorious and 60 percent of independents agree. Among Republicans, 44 percent think Democrats will win the White House and 45 percent think their party will hold on to the presidency.

Yet, Giuliani basically ties with Clinton and Obama in head-to-head matchups, according to the poll.
