"How, by the way, can Ted Cruz keep going after tonight? Trump is on track for either a sweep or near-sweep of Indiana’s delegates, which will bring his goal of obtaining a delegate majority that much closer. There's almost no way now that Cruz can stop him, in fact. So what’s the point of carrying on?"
Simple, guys, and I can't figure out why you didn't think of it. The answer: cheating. This is the party, after all, that has cemented its control on the House of Representatives by Gerrymandering and voter suppression, and the party that held the White House from 2000 to 2008 through the actions of a corrupt Supreme Court. They still have two good months to rig the convention process to overthrow Trump. Is there anyone out there naive enough to think that the Republicans don't have "consultants" all over the place working full blast ever minute of the day to figure out a way to do this and get away with it?
And that is all the Republican primary contest comes down to at this point: can the real masters of the Republican party find a way to force their candidate on the party without causing a catastrophic explosion? Because there is absolutely no question that, if they can figure that one out, they will do it.
