U.S. Rep. Joe Sestak isn't backing down from his plans to run against Sen. Arlen Specter next year in the Democratic senate primary. The Washington Post reported today that Sestak is assembling his campaign team, which will likely include media consultants The Campaign Group.

We spoke to J.J. Balaban, of The Campaign Group, who said they would be excited to work again for Sestak if he enters the race. The media operation did his 2006 and 2008 campaigns for the U.S. House.

"I think Joe Sestak would give Arlen Specter the race of his life," Balaban said. "Arlen has 30 years of Republican votes he'd have to explain to a Democratic primary electorate. It's pretty hard to explain to Democrats why you voted for George Bush's tax cuts, why you voted for the war in Iraq."
