George Stephanopoulos has announced that he’ll be moderating the first general election debate between Pat Toomey and Joe Sestak, vying to replace Arlen Specter as Pennsylvania’s newest senator. Toomey leads Sestak by 9 according to Rasmussen.

The first debate will held on Wed., Oct. 20th in Philadelphia’s Constitution Center and will be broadcast statewide. Toomey and Sestak have also confirmed a second debate for Friday, Oct. 22 in Pittsburgh.

With two debates just days before Election Day, each candidate must be hoping to send a powerful message to that 7 percent slice of undecided voters.
