The Democratic Senatorial Campaign Committee is indicating that freshman Republican congressman Tom Cotton of Arkansas is on the group's radar. From Politico's Alexander Burns:
DSCC call slams Tom Cotton -- not an announced Senate candidate -- for supporting Ryan-style budget

Cotton, who was first elected to the House in 2012, has been named as a possible 2014 Senate candidate to challenge Democratic incumbent Mark Pryor. But as Burns notes, Cotton has not announced he's even thinking of running for the seat.
