McCain complains that Gingrich has done “something that we don’t do in politics”

Which arguably, is tell the damned truth:

SidJohn McCain slammed Newt Gingrich Thursday for calling Mitt Romney “a liar,” accusing him of crossing the line of “something that we don’t do in politics.”

“I don’t think it’s appropriate to call your opponent a liar. That’s just something we don’t do in politics unless you certainly have some overwhelming proof,” said McCain on CBS’s “The Early Show.” The Arizona senator endorsed Romney on Wednesday in New Hampshire.

In an interview earlier this week, Gingrich called Romney a liar about his own record and beliefs.“He’s not telling the American people the truth,” Gingrich said. “It’s just like his pretense that he’s a conservative,” he said. “I just think he ought to be honest to the American people and try to win as the real Mitt Romney, not try to invent a poll-driven, consultant-guided version that goes around with talking points. I think he ought to be candid. I don’t think he’s being candid.”

You might recall that Mr. McCain used the tyranny of nice to repudiate those who were using President Obama’s entire name during the 2008 campaign.

How’d that work out for you John Sidney McCain?

About as effectively I imagine as this is going to work.

We appreciate your service Senator McCain… but that’s frankly about it.

Who needs three branches of government...
