The question you should ask is how many red states Trump will turn blue. Start with Georgia, Arkansas, Tennessee, Indiana and Kentucky. Following debates, more follow. The Senate becomes Democrat majority again.
Cruz runs significantly better against Clinton in every poll. He holds the Senate, he wins Nevada and Colorado.
I underestimated Trump’s weakness..he even loses Arizona to Clinton by 7%.
Trump won all the states on your list whose primaries have been held. He's ahead in Indiana polls, I believe. So what is the basis of your argument, other than wishful thinking?
