“To use a sports metaphor, Trump is the lead blocker who blew a hole in the opposition line so Cruz, the ball carrier, could run thru the hole.”
While it’s true that Trump blew things up, he didn’t do it to help Ted Cruz. Any hole Trump made, has been plugged to keep Cruz out, just like the Mexico Border Wall Trump will build as President.
Cruz supported building a wall while Trump was still supporting amnesty.
