Not nearly as much as they're hurting US!!!
Stupidity and arrogance SHOULD hurt. Unfortunately they don't.
Although still somewhat of a long-shot, a Republican Senate takeover could help torpedo a potentially disastrous lame duck session. Although there would be some very vindictive Dim lame ducks, there would be more frightened incumbent Senators. Senators like Nelson of NE, Landreiu of LA, and other plain states cannot consider cavalierly passing cap and trade, union card check without antagonizing their constituents. Rino Senators in ME and MA will also think twice before siding with the Dims. The Senate obviously has a greater capacity to slow down hasty legislation.
