Former U.S. Attorney Tim Griffin -- the former Bush campaign opposition researcher whose appointment was at the center of the U.S. Attorney controversy of 2007 -- is not running for Senate after all.

Griffin had been eyeing a possible Senate bid in his native Arkansas, against Democratic incumbent Blanche Lincoln. But as the Arkansas News reports, Griffin is choosing instead to focus on other priorities: He has a growing family, he's making his way up in the Army Reserve, and he's advising a bunch of political campaigns.

So that's one lingering piece of muck from the Bush years that we can probably lay to rest -- at least for the immediate future.
