Cruz , if he wants to be future presidential material, had better get behind Trump around June 7th or shortly after.
Now I live in PA, not Texas but if he does not do the above, this is what the rest of the country is going to remember about him:
1) when a crowd of socialists, illegal immigrants and BLM thugs shut down Trumps forum, Cruz stood on the side of the left and blamed Trump for that incident.
2) He literally could not take the heat of the campaign, melting down in a 10 minute diatribe on the last day of his active campaign. A Muskie moment, for those old enough to recall. Not good.
3) After it all he refused to take the olive branch offered. Even though he signed a pledge to get behind the parties choice. Of course he has a few weeks to do this.
If he does not endorse Trump soon (in weeks)prior to the convention, well a cynical person would say he is hoping Trump is not elected so he will have a change in 2020. Not good. It implies he think more of himself than any supposed principle. I do not know about his adopted state, but for ~85% of folks here he would be dead to us in 2020 or beyond if that comes to pass. I suspect that would be true in most of the nation, though I cannot speak for other areas.
I think it may be best for Trump if Cruz does NOT endorse him until the convention.
As runner-up he gets a primetime speaking slot.
It would have more impact if he did it then, forcefully.
Of course he can’t be critical of Trump in the meantime.
Sooner rather than later...
And #4, no matter what anyone thinks of Trump, he was chosen against all odds with a RECORD number of votes by the PEOPLE.
Trump is not a candidate like Romney, shoved down our throats by rigging the process. Trump will be the nominee despite the shenanigans!
