Mitt Romney was on Fox News Sunday this morning, and his interview went well overall.

But Romney is doubling down on his claims that Newt is an unreliable conservative because of Newt’s comments last spring about the Ryan Plan and “right wing social engineering,” and his couch video with Nancy Pelosi.

As I have pointed out before, Romney did not back Ryan at the time and said he would bring forward his own plan.  It turns out that Newt was right that the Ryan Plan as originally conceived was a plan too far, and even Ryan has walked back from it.

Romney this morning said that Newt was unreliable because he tried to cut the legs out from under the Ryan Plan at a critical juncture.

Talk about cutting the legs out from a conservative agenda at a critical time, what Newt did last spring was nothing compared to what Romney did in 1994 when he ran against the Contract with America and ran away from Reagan during his race for Senate.

It is what euphemistically is called Romney’s 1994 Problem.

Romney tried to undercut the greatest conservative achievement in a generation for his own political gain.

Being an unreliable conservative is not an accusation Romney should be making about others.
