Of the 55 Republicans how many are really Rinos?

There are 4 hard core RINO's: Specter, Collins, Snowe, and Chaffee. That brings the 55 down to 51
Then you have Warner (VA), Stevens (AK), and Huchison (TX), who have voted in support of Roe in the past. In that sense of the Senate resolution that was attached to the PBA ban. They'd bring the 51 down to 48.
Then you have the "wild cards" McCain and Hagel. Bringing the count of real Republicans down to 46. And Lisa Murkowski is pro-choice so bring it down to 45.

So depending on how strict you grade, the answer is between 4 and 10 out of 55.

But how many DEMS are anti-abortion ?

[UnbelievingScumOnTheOtherSide]

If ALL the hard core RINOS left you COULD lose the Senate, barely. But then the Dims wouldn't have any spies, moles and provocateurs at Republican strategy sessions. Therefore they won't do it.

Scary!, McCain would do it too. I trust him about as much as I trust Specter.
