Barack Obama Makes Final Push for Charlie Crist in Radio Ad

Former Gov. Charlie Crist is getting a little help from the president himself this Election Day -- on Tuesday, President Barack Obama featured in a new radio ad urging voters to cast their ballots to send Crist back to Tallahassee.

The Miami Herald reported Tuesday that the ad has been airing since Monday on a Miami radio station.

"If you want to raise Florida's minimum wage, go vote," Obama says in the ad. "If you believe that every child deserves a fair shot, and that it's wrong to cut scholarships and funding for schools, go vote. If you want a governor who will fight for you, not just the wealthy and the powerful, go vote for Charlie Crist."

Virtually every poll has Crist and Gov. Rick Scott in a dead heat. Voting ends at 7 p.m. ET.
