(CNN) - A day after one candidate dropped out of the race for the Republican Senate nomination in Florida, a new candidate jumped into the hunt for the Democratic nomination.
Florida real estate investor Jeff Greene launched his bid Friday, a day after Florida Gov. Charlie Crist announced he would no longer run for the Republican Senate nomination and instead would continue his campaign as an independent candidate - leaving former Florida House Speaker Marco Rubio as the sole GOP contender.
Greene appears to be running as an outsider.
"I'm just as frustrated as you are. That's why I am running for Senate this year. For too long, the career politicians we've sent to Washington have played partisan games and have failed us." Greene told Florida voters in a press release and video announcing his candidacy. "I am an outsider, the only candidate who isn't a career politician."
While Greene is new to the game, he does appear to have a big advantage over the leading Democratic candidate in the race, Rep. Kendrick Meek. And that advantage is money. Greene's a billionaire and if he spends his cash freely in the Senate bid, it will come in very handy in a state as large as Florida, with multiple expensive media markets.
Greene's campaign tells CNN that the candidate is willing to spend whatever it takes to win the seat. A statement from the campaign says he'll refuse campaign contributions from special interests, and will limit individual donations to $100.
Greene, 55, made millions investing in real estate and multiplied that money by investing in credit-default swaps during the real estate bubble of recent years.
That could come up in his campaign, as could his personal life. According to a Forbes profile of him from a year and a half ago, Mike Tyson was best man at Greene's 2007 wedding and he put up friend and former Hollywood madam Heidi Fleiss as a house guest for a year.
UPDATE 4:05 p.m: Meek's campaign put out a statement Friday afternoon reacting to Greene's entry into the race.
"I'm running for the Senate to stop Wall Street from ever again wrecking the Florida economy. Jeff Greene profited from the misery of millions of Americans who lost their home equity, if not their homes. That's not the kind of candidate the Democratic party needs, and it's not the kind of senator Florida needs," says Meek in a statement.
