|Debbie Wasserman Schultz|
Number one: Assume that Donald Trump will be the Republican nominee, when it is clear he will not. There's some pretty good reasoning and not too shabby math in this conclusion but Trump, like Bernie Sanders, has had his share of surprises in this race that has kept the former in the lead and the latter in a very strong contender's position.
Number two: The Dems attempt to nominate the only one of the two Democratic candidates who is almost guaranteed to reunite the Republican Party. You think Mitch McConnell hates Barack Obama, there is nothing that will bring the GOP together quicker than its hatred of the Clintons. Huff Post says, "Hillary Clinton is one of the least popular major-party politicians in America, and her disapproval rating is not just sky-high among Republicans..."
We can thank Debbie Wasserman Schultz for the direction of the Democratic nominating process, something she has clearly steered to favor Hillary Clinton over Bernie Sanders. Sanders ratings against Trump and Cruz are better than Clinton's but due to Schultz' close ties with her and the fact that the Bern is an Independent, the DNC Chair is hell-bent on pushing him out of the race.
