The former President explained his problem with Speaker Gingrich, “I had a conflict with him at one point,” Bush told the Houston Chronicle. “I’m not his biggest advocate.” Bush made clear he is only “backing” Romney, not “endorsing him.”

It seems the former President’s trouble with Mr. Gingrich is the Speaker took him seriously in 1988-1990 when he told the Republican convention and the nation, “Read my lips, no new taxes.” Then, two years later “Read My Lips, No New Taxes” Bush had the Republican and Democrat leaders in the oval office to agree on his new tax increase. He had “not quite leader” Gingrich, “Right outside the Oval Office.” Presumably there were other “not quite leader” Democrats and Republicans out there as well.

But when President Bush and the joint congressional leadership were ready to take their “props” out to the Rose Garden to announce the new tax, Gingrich was gone. He had gone back to the Capitol to begin to lobby against the new tax. Now we understand the conflict. Now we understand. You, Mr. Bush 41, certainly couldn’t expect to be “his [Gingrich] biggest fan.” Yes, someone who took you at your “Read my lips, no new taxes” word and then didn’t go along when you recanted would be a—what’s the word? Oh, right, “bomb thrower.”

We can assume Governor Romney is not a “bomb thrower” and could be counted on to go along with a broken promise. Is it possible Governor Romney is so reliable he would actually break his own promises? We don’t know. Remember Romney only has “41’s” “backing”—not his “endorsement.”
