McCain projected to win; Florida newcomer shakes up establishment

(CNN) – Two wealthy candidates in Florida spent a lot of their own money on campaigns. Rick Scott's investment paid off. Jeff Greene's investment didn't.

Scott, a millionaire political newcomer, defeated the state's Attorney General Bill McCollum on Tuesday in the Republican primary for governor, CNN projected.

Scott spent $50 million of his fortune since joining the race in April. He claimed victory in front of supporters and alluded to the divisive nature of his fight against McCollum, the party-establishment favorite and former congressman.

"Some of you may have noticed this was a hard-fought race. We talked a lot about our differences, but tonight it's time to remember those things that bring us together - to recall our core beliefs and recommit ourselves to fighting for our principles," Scott said. "The Republican Party will come together, and the reason we will come together is our shared devotion to the values that make America great."

Scott was ahead of McCollum, 46.5 percent to 43.3 percent, with 92 percent of precincts reporting, according to The Associated Press.

The winner will face a November general election against Alex Sink, the state chief financial officer, whom CNN projected will win the state's Democratic primary for governor.

In a different race featuring a political veteran against a self-funded candidate with deep pockets, Rep. Kendrick Meek declared victory over billionaire Jeff Greene in Florida's Democratic primary for U.S. Senate. Meek led Greene 55.9 percent to 32.2 percent, with 78 percent of precincts reporting, according to The Associated Press.

Meek will take on Marco Rubio, whom CNN projected will win the Republican primary for Senate, and Gov. Charlie Crist, a Republican-turned independent, in the general election.

Meanwhile in Arizona, Sen. John McCain won the GOP Senate primary after a bitter campaign against former U.S. Rep. J.D. Hayworth, according to a CNN projection.

McCain, seeking a fifth term as senator, was ahead, 59.3 percent to 30.1 percent, with 50 percent of precincts reporting, according to The Associated Press. FULL STORY
