There is enough of a race that Trump does not need to lose focus.
1237 baby, don’t let up until you it in hand!
I just went through and pretty conservatively assigned delegates to Trump based on the upcoming primaries. There were a lot of states that I gave him zero delegates — and I STILL came away with him only needing 65-70 California delegates to get to 1,237.
Don't let up until you've won every delegate you can, past 1237.
Cruz and the GOP-E (but I repeat myself) will try to turn delegates that Trump has won.
