Romney and Obama Battling to Win Over Undecided Voters - kcentv.com - KCEN HD - Waco, Temple, and Killeen

(KCEN) -- The first presidential debate is tomorrow night and both candidates are rehearsing their talking points to win over undecided voters.

Mitt Romney is hoping to pick up a few votes with an endorsement from football great John Elway.

President Obama is taking the personal approach and has a lead in all nine of the key battleground states.

Larry Sabato of the UVA Center for Politics said, "Romney's task is difficult because he has to redefine himself as well as redefine the election."

The first debate is on the domestic issues that are defining this election.
