Richard Corcoran’s role in that Sarasota House seat loss

No Republican, probably including Buchanan, is more to blame for the loss than Donald Trump. Let’s stipulate that. Not only has the president energized Democrats like never before, but he has apparently has turned off enough old line Republicans (especially women), that thousands of Republican votes went to the Democrat.  Also, you no longer run the the Republican House campaign operations. Your successor, Jose Olivia, is supposed to be doing that.
