Republican Jeff Flake and Democrat Richard Carmona will square off in a debate Wednesday in the race to fill the U.S. Senate seat being vacated by retiring Sen. Jon Kyl.

The one-hour debate marks the first of three general-election debates the candidates will have before election day.

The other debates are scheduled for Oct. 15 in Tucson and Oct. 25 in Yuma.

Flake is a six-term congressman.

Carmona was surgeon general under President George W. Bush.

After the debate, former President Bill Clinton is scheduled to appear at a rally in Tempe for Carmona.

Voters can begin casting ballots on Thursday.
