Well, of course Rick Perry says he's now going to take another look at running for president. Wouldn't you?

The guy recently became the longest-serving governor in Texas history, and now he looks at a Republican field led by the former governors of three states - Massachusetts, Minnesota and Utah - whose combined populations don't come close to the number of Americans who live under the lone-star flag. Given how wildly uninspired Republicans are searching for another candidate to drag into the race, you would think a successful governor like Mr. Perry would need a pretty compelling reason not to run for president.

As it happens, such a reason might just exist.

Republicans talk about something called "Bush fatigue." It almost always comes up in relation to Jeb Bush, the brainy and politically talented brother of George W. Bush, who was himself the popular governor of a pretty sizable state. It's a common theory in conservative circles that while Jeb (everyone calls him Jeb) might be the most formidable candidate out there to challenge President Obama, he is nonetheless cursed by his last name.
