ED MORRISSEY: Senate GOP for 114th Congress has not reached its ceiling yet. “There is a potential ceiling here of 57 seats for the Republicans, and certainly 56 is within the realm of probability. That would make it very difficult for Democrats to win back control in 2016, as the odds get much longer after one gets to R+53 in the Senate. King would flip back if they got close enough for it to matter, but Manchin wants to win re-election in West Virginia and the progressive tilt of Democrats and the legacy of Barack Obama practically force Manchin to realign himself, and sooner rather than later. I’ll predict that the 114th Congress starts with at least 55 Senators in the Republican caucus. Those are the consequence of wave elections, and of setting precedents for abusing the minority in the years preceding them.”
