Mark Pryor will remain in the senate. Bloomberg's attack ads over Pryor's vote against expanded background checks are actually strengthening Pryor here in Arkansas. Cotton has yet to announce, and has signalled that he may NOT run against Gramnesty, Jr. Yes, THAT Gramnesty. Pryor is a less-reliable Democrat that Lindsey, but just as gay and almost as liberal. Cotton may wait so long to get into the fray that Pryor will already have him so "Romney-ed" that he will not be able to recover; the disingeneous defining of Cotton by the Pryor campaign has already begun in earnest.
