SACRAMENTO — The Republican Party will hold a presidential candidate debate at the Ronald Reagan library Wednesday. It’s a bad fit. The GOP’s modern idol is exactly the opposite of Reagan in personality and character. For upbeat Reagan, America was a “shining city on the hill.” For whining Donald Trump, it’s a waste bin for venom and lies. Reagan’s soaring rhetoric made people feel good about themselves. There was “always a bright dawn ahead” — “Morning in America.” Yes, maybe that was a tad naive and corny, but it brought a collective smile — and won over many Democrats.
