We also talked to Aaron Sharockman with PolitiFact Florida about whywe're seeing so many "half true,""mostly false" or "mostly true"statements rather than a hard "true" or "false."

While arguing whether the stimulus was worth the hundreds of billionsthat it cost the government, Paul Ryan said, "Was it a good idea tospend taxpayer dollars on electric cars in Finland, or on windmills in China?"

PolitiFact Florida rates this claim, MOSTLY FALSE.

While discussing Medicare, Vice President Joe Biden attacked theRepublican ticket's proposal for Medicare, saying Romney and Ryan would"eliminate the guarantee of Medicare."

PolitiFact Florida rates this claim, HALF TRUE.

Paul Ryan said this about unemployment: "They passed the stimulus.The idea that we could borrow $831 billion, spend it on all of thesespecial interest groups, and that it would workout just fine, that unemployment would never get to 8%-- it went upabove 8 percent for 43 months. They said that, right now, if we justpassed this stimulus, the economy would grow at 4 percent. It's growingat 1.3."

PolitiFact Florida checked the claim that Obama promised that unemployment would never go under 8%. That rates MOSTLY FALSE.
