Those issues are going to persist in the states wehre he played those games, just as Ron Paul zealots created some issues.
And if the party allows Cruz to control the convention, you better believe it, the people will see that as the party facilitating the shenanigans, against popular will.
At any rate, my general point is that the party has more control over this than Cruz does, and Cruz really has not the power to damage the party. Cruz staying in does not damage the party, the party still has control of its own fate.
If Trump WINS tomorrow, big donors will dry up for Cruz!!! Cruz WILL be TRUMPED!!!!
