The target list is a mix of Republican freshmen and GOP challengers. The group hits Reps. Dan Benishek (R-Mich.), Chip Cravaack (R-Minn.), Bobby Schilling (R-Ill.) and Daniel Webster (R-Fla.) and runs ads against the opponents of Reps. Bruce Braley (D-Iowa) and Ron Barber (D-Ariz.). The SEIU chipped in to fund the ads in Florida and Minnesota.
The total ad buy is $1.2 million.
Cravaack, Schilling and Benishek are all locked in toss-up races, while Webster is facing a tough opponent in a GOP-leaning district. Barber and Braley appear to have the edge in their races.
