ORLANDO, Fla. (AP) - Democrats Jeff Greene and Rep. Kendrick Meek will meet for their third debate.

If Tuesday's debate is anything like the first two, there will be a lot of fireworks.

Greene, a billionaire who jumped into the race on the last possible day, says Meek is a career politician that typifies the problems with Washington.

Meek says Greene profited off the misery of others when he made investments that made him hundreds of millions of dollars on property foreclosures. He has referred to Green as a "bad person."

The primary will be held Aug. 24, but early voting is already underway.

NCIS will air at 1:37 am following the Late Late Show with Craig Ferguson.
