ORLANDO, Fla. (AP) - The League of Women Voters and PBS have called off televised debates in Florida's U.S. Senate and governor's races.

The reason: a lack of candidates.

The sponsors said they'd lined up Gwen Ifill and Judy Woodruff of PBS's The NewsHour to moderate the debates Thursday in Orlando.

They couldn't, though, get commitments from either Republican, Senate candidate Marco Rubio and gubernatorial candidate Rick Scott, nor from Gov. Charlie Crist, who left the GOP to run for the Senate as an independent.

The two Democrats, Senate candidate Kendrick Meek and gubernatorial candidate Alex Sink, accepted, but the League and public TV system don't allow empty chair debates.
