This is unfortunate. Peg has filed already with the FEC and is a declared candidate. Toomey assured her he wasn't getting in to this and has been making noises about running for Governor. That's what he should do.
A Conservative ticket in 2010 with Toomey for Governor, Luksik for Senate, and Russell for Congress will invigorate the PA electorate. The three standing together will prove to be formidable.
