There is a major difference here:
When Gingrich supported Dede’s candidature, he was not running for any official office. Newt had no other interest than GOP candidates to be elected.
Santorum supported Specter in 2004, because Specter supported Santorum in his 2006 reelection bid. Same payback between the two as in 1995.
So, IT ISN’T THE SAME THING.
No it isn't. Specter Sphincter was a long time sitting senator. A party seldom supports a challenger to a sitting senator in its own party.
Dede was a pro-abort, pro-gay marriage would-be 'rat who threw her support to the 'rat when she saw that republican voters wold have no part of her.
