CQ Politics is reporting that Dems are now "surging" in Colorado, and it has changed its ratings of two races accordingly: The contest between Dem Ed Perlmutter and GOPer Rick O'Donnell has moved from "No Clear Favorite" to "Leans Democratic," while the race between Dem Rep. John Salazar and GOP challenger Scott Tipton moves from "Leans Democratic" to the less-competitive "Democrat Favored." Relatedly, Kos points to an internal poll done by Dem challenger Angie Paccione showing her in a dead heat with GOP Rep. Marilyn Musgrave, and asks: "Is it real? Accurate? If so, she may have weathered one of the fiercest full frontal assaults of any Democrat this cycle."
