He's just fine the way he is.
I would rather vote for a conservative like Cruz (I have the t-shirt) than just an American like Trump.

Cruz is preferable. He can’t win in November. Look up the math. Presidential politics requires a larger than life personality. If Trump can deliver New York, he wins.
If the GOP really wanted to be rid of Trump all they would have to do is change their behavior. They have been bad, Trump is the stick we have to whip them with. If they had been good they would not be dealing with Trump. It is that simple.
