Their strategy of teaming up is likely a lose/lose proposition.
Unless I’m wrong, Kasich is still on the ballot, and I don’t believe his supporters are particularly fond of Cruz. My thinking is the more press this partnership gets (and it’s getting plenty on cable news), the more this gives credibility to the Trump campaigns claim of a rigged system.
It will be interesting to see poll results in the next few days.
I think the Kasich voters understand what to do to get their candidate a chance.
