Never is a long time. I'm not a fan of categorical statements, either. Still, I'm 100% certain of this much -- I will never vote for, or support, or otherwise aid, Donald Trump. He's a menace. He's run a low, mendacious, generally substance-free campaign. He's too lazy to learn the issues and his instincts consistently lead him in the wrong direction. He would be a disastrous candidate and, if somehow he won the general election, an even more disastrous president.
I have spent months trying to understand where Trump's support is coming from. I do believe many Trump supporters mean well -- the frustration many feel about the world is real and entirely legitimate. Still, the people around Trump and his campaign are cynics at best, nihilists at worst. At a time when we need the most principled conservative we can find to run against the utterly unprincipled Hillary Clinton, there's a good chance this process is going to deliver someone as unprincipled as she is. I can't be part of it.
To my mind, the Republican Party should do whatever it takes to stop Trump. If that means getting behind Ted Cruz or John Kasich, fine. It it requires a smoke-filled room, so be it.
