Byron York makes a solid point in that I’d rather run scared and keep the scare up than slack off and finish with on 52/53 Senators from the GOP. While it is unlikely that Alaska’s Sullivan will lose, at the moment there are ‘only’ 52 Senators and the same math that was favorable in 2014 is decidedly against the GOP in 2016 for the number of contested seats. I’m sending my money to Cassidy for this run-off, it is that important.
Not only that, but there are several “edge” Republicans in the Senate who often vote with the Democrats, or compromise bills into messes. 54 is a lot better than 52.
