Yes and Cruz needs to GTFO after April 26th. He is on life support now.
It's 744-559 now. There is a high probability that Trump won't have the 1237 by July either. There is NO reason for Cruz to drop out. He is one of two viable candidates with a large part of the vote (and winning the GOP states to Trump's Liberal states, outside of the Old South), heading into a likely Brokered Convention.
If nobody gets 1237, the Convention should hand it to one of those two candidates. The GOP will likely try to force in a third alternative, but they would be making a huge mistake. Cruz can still make a claim to the nomination because he has won many states, is within striking distance of the leader, and a large part of the lead was built back when there were 17 candidates. In a 2-man race, with Trump NEVER topping 50%, Cruz could have won.
Cruz has topped SIXTY percent in more than one state, and Trump has yet to beat 49.3%. Cruz did it in very Conservative states, but Trump's best states are/will be MASS, NY, and CT... the most Liberal area of the nation. This says a lot.
In the end, the Trump celebrity-worshippers and the GOPe are going to hand the election to Hillary, despite 75% of the nation, in both parties, wanting something other than the Same Old Same Old... Hillary ,who has strode atop the DC pyramid for 24 years so far. We are a pathetic electorate.
