Let’s be honest about this, both Senators with 95% conservative ratings are quitting the senate because they know they cannot win the Republican primaries in their states thanks to the success of Donald Trump. But to Trump’s yet realized horror, they will still be Senators for another year and a half.
Adding John McCain, Lisa Murkowski, Susan Collins and Rand Paul that makes SIX senators Trump cannot count on.
On the good side this means the GOP tax plan for the rich has little chance of going anywhere. On the bad side this means that in the 35 GOP held states there will be a large new crop of radical know nothing Trumpers coming to the Senate in 2019. No matter how ignorant or radical or awful they may be, in the majority of the red states they will beat any Democrat by at least 10 points.
