What a brilliant strategy. Insult all Trump’s supporters in the full, confident assurance you will never need any of them to switch to supporting Cruz.
Because if you do suspect Cruz may one day need some of Trump’s supporters, calling them names/stupid is the best way to assure you will never get them.
With all the crap I hear from Trumpsters, that is truly funny. For the record, and for about the twentieth time, I haven't picked a candidate to support. So your thesis is baseless.
