Rep. Brad Ellsworth (D-Ind.) continues to base his ad campaign on his time as a sheriff. The congressman's second TV spot of the Senate race, released Wednesday, even goes so far as to feature footage of Ellsworth in his Vanderburgh County Sheriff's uniform. His first TV ad, titled "At Stake," featured Ellsworth talking about him time as sheriff and was notable because he didn't mention serving in Congress.

The new ad, titled "Think," will air in two-thirds of the state, according to a spokeswoman for Ellsworth. The ad is airing in "areas where voters are less familiar with Brad than they are in Evansville, Terre Haute and Louisville. It includes both cable and broadcast," Liz Farrar said in an e-mail.

The two-term congressman faces former Sen. Dan Coats (R-Ind.) in November. 

The Washington-based firm Dixon/Davis Media Group is producing Ellsworth's campaign ads.
