The news of Sen. Arlen Specter's decision to switch parties and run for reelection as a Democrat has only spurred the Club for Growth, the group's vice president for government affairs tweeted Thursday.

The Club's Andy Roth tweeted:
The Club for Growth seems to be the center of attention lately. I can't keep up with the media hits. People are joining CFG in droves! #tcot

The Club has been a major topic of discussion in Republican circles, especially on Twitter, since Specter's decision. Specter's potential Republican opponent in 2010 will be former Club for Growth Chairman Pat Toomey.
