Why hasn’t Sanford endorsed McCain this year?  That question has come up all over the place.

Perhaps it’s because they don’t have anything “in common.”

We find it funny that both of these stories popped up on our radar today.

In the State:

To date, Sanford has refused to endorse a presidential candidate even though his pick in 2000, U.S. Sen. John McCain of Arizona, is running again.

Later in the same story:

Last week, the Club for Growth, a nationally prominent group of economic conservatives who have supported Sanford in past elections, announced that three of the top 2008 Republican candidates would speak at its winter forum at the end of March in Palm Beach, Fla. Also scheduled to appear: Mark Sanford.

And:

When Sanford heads to Palm Beach for the Club for Growth meeting later this month, he’ll be among friends.

Club CEO and president Pat Toomey said last week that it’s “unfortunate” that Sanford has said he’s not going to run for the White House.

“He’d be a great candidate,” Toomey said. “What Washington desperately needs is someone who can instill fiscal discipline, limit spending and keep taxes low. And I have no doubt at all if he were on the national ticket, Mark Sanford would be moving in that direction.”

And then this story popped up today:

“The reason why we don’t have a majority in the Senate today is because of the attacks Club for Growth made on Lincoln Chafee, the senator for Rhode Island. A liberal Republican senator, but would have voted for Mitch McConnell to be Majority Leader of the Senate.”

“They have continuously attacked Republicans they don’t agree with. I believe in a big tent party. I believe there is room for someone from Rhode Island who may not agree with everything I agree with. But I still want him in the Republican Party. That’s not the case with the Club for Growth. I’m not really sure what the Club for Growth and I have in common.”

So why hasn’t Sanford endorsed McCain? Could it be that Mark Sanford is smart enough to know where his bread is buttered?
