The political process is such a joke. Trump is clearly the best GOP candidate they could field. He's well-known, successful, and has broad appeal. He has the most support among moderate conservatives. He has the most support among (!) evangelicals. He has the most support in the northeast, AND he has the most support in the south, two regions which are basically polar opposites. He excites the base, he attracts new Republican voters, and he's the candidate who would be able to swing the most Democrats. He's well-connected with the rich and also a populist.
But he's likely to not get the nomination because the party bosses can't handle the idea of nominating someone who's not in their pocket. They are desperately clinging to Cruz, but don't kid yourself, it's not because anyone actually wants Cruz to win. It's all a ploy to stop Trump from getting to 1237. If the tables were turned and Cruz were ahead, they would rally behind Trump in the exact same way. Get a brokered convention so they can install their own puppet. It's disgusting.
Trump is basically the perfect GOP candidate to win in 2016 but the party is too busy throwing a temper tantrum. This is why I have no hope left for American Politics. No honest person can succeed as a politician in this country.
