For the many it will turn-off, it's also turning on far more converts to the GOP than ever before.
All these polls showing Cankles beating Trump nationally are BS because they are all taken using "Likely Voters," i.e., people who voted in 3 of the last 4 cycles.
This doesn't include the Trump voters who usually don't vote or who never voted before. Their heads are never counted in these polls, and it's just as well. They are almost too numerous to count, as you'll see next November.
It is this voting bloc that has GOP's 2016 turnout up over 100% nationally. Hillary is going to run into a D-10 Caterpillar (huge bulldozer).
I absolutely agree with you, and I wish more conservatives would see Trump in this manner. Cruz cannot win the general electon, regardless of polls 7 months away, he does not have the support to win swing states. Trump has proven he does. Please, we need to band together to stop Hillary, put aside aversion to Trumps mannerisms and give the man a chance. He has already succeeded against all odds.
