Mitt Romney entered the presidential race with a lot less name recognition than the likes of Rudy Giuliani and John McCain — so in order to get to the top, he's had to spend a lot of money, including much of his own. So despite out-raising the rest of the GOP field, Romney no longer leads the race in cash on hand.

Romney now has less cash on hand than Giuliani — $9.2 million to Rudy's $12 million — and has spent a stunning $52 million up through the third quarter compared to only $30 million spent by Rudy.
