Specter said Toomey, in his work as chairman of the conservative Club for Growth, was the Democrats' "Most Valuable Player," copping a sports analogy, for having contributed to the defeat of centrist Republicans in Congress.
Specter tweeted Wednesday:
Pat Toomey, the Democrats' MVP. How Toomey cannibalized the GOP: http://tinyurl.com/cxlpfc
The link follows through to a page on Specter's Facebook profile, in which Toomey is blasted for contributing to the defeats of Sen. Lincoln Chafee (R-R.I.), Rep. Ric Keller (R-Fla.), Rep. Wayne Gilchrest (R-Md.), Rep. Tim Walberg (R-Mich.), Rep. Bill Sali (R-Idaho), and Rep. Heather Wilson (R-N.M.).
The tweet represents a consistently aggressive but particularly harsh line of attack from Specter, who has sought to get out in front of the sure to be hotly-contested primary battle.
