The good news is that the number of Cruz cultists are diminishing by the day.
That is true. I have seen a lot of posts lately saying that this or that that Ted Cruz did made them decide to switch to Trump. A Jewish friend of mine who just a week or so ago posted on Facebook one of those Trump is scary like Hitler articles. Then she watched his speech at AIPAC and said she might vote for him.
The people still for Cruz who are here are really supporting Hillary. After March 15, it is beyond all hope for Cruz to win the nomination. He can only deny a first ballot win to Trump, and that is unlikely. If he did succeed at that, he would not get the nomination (GOPe still hates him), and the acrimony would be so great that Hillary or whoever the Dems nominate would win.
So, supporting Cruz at this point is supporting HIllary.
