That may be the case, but this scenario has the potential to blow up in his face.
Lets say Cruz has a good 30-40% support base at this time. Why make that support base hate your friggin guts forever?
You might succeed in taking Cruz out, but you wont win the general.

Trump has spent his entire adult life as a bare kncukle brawler. He assumes that when he is done with Cruz he will win over his voters.
Foolish assumption IMO. But his followers love this crap as ou can see here.
I hope Trump is smarter than that. His scorched earth tactics are going to blow up in his face November.
It’s plain to see that he won’t.
This is like trying to defeat your opponent by hosing him and yourself in gas and then lighting a match.
The only one that benefits from the primary being dragged into the crapper is the GOP.
