No he should not drop out yet. But, after a few more states go the way of Trump, then I think it will be time for him to bury the hatchet and drop out....but only if Kasich is already out.
There is no way Cruz should drop out if Kasich is dumb enough to stay in the race.
I don’t think Kasich will drop out.
The RNC seriously want Kasich to be the nominee.
