Not even close.
LOOK at this record. On Life and Marriage, he's a social conservative but what about everything else? You're not troubled by his yes vote to confirm Sonya Sotomayor when Clinton nominated her for the 2nd Circuit when everyone knew she'd be fast tracked to the Supreme Court and low-and-behold she was Obama's 1st choice! Even McCain didn't bite that Apple. How about choice of Spector over Toomey in the primary? How do you cope with his introducing and voting for a half-billion additional funds on top of the $900 million Amtrak budget? What on earth is conservative about that?
He's, at best, the GOP establishment's version of a Blue Dog Democrat. He's is a snake oil salesmen in sweater vests preying upon those who care deeply about traditional marriage and prolife issues.
We already know that Romney is not a conservative. And Gingrich has been at various times on the other side on such issues as global warming, the individual mandate for health care, a current supporter of the prescription drug program (a $7.2 trillion unfunded liability), and an advocate of amnesty. Newt supported Dede Scozzafava over Hoffman. And that is just the tip of the iceberg. What kind of Conservative holds those positions?
