It boggles my mind that some conservative G.O.P. members would vote for Hillary Clinton or not vote at all if Donald Trump gets the Republican nomination. That's like cutting off your nose to spite your face. They totally ignore Reagan's “80% Rule” which states that a Republican should vote for the Republican candidate who agrees with 80% of what you believe. Whether you love or hate Donald Trump, I'm sure his views would meet that 80% plateau as compared with the 0% that Hillary Clinton (or Bernie Sanders) has spelled out.
