I've been a conservative my entire life. ... So you'd think that the Conservative Political Action Conference, or CPAC, would be a natural fit. It once was. But on Saturday, after speaking to this year's gathering, I had to be escorted from the premises by several guards who seemed genuinely concerned for my safety. What happened to me at CPAC is the perfect illustration of the collective experience of a whole swath of conservatives since Donald Trump became the Republican nominee. We built and organized this party - but now we're made to feel like interlopers.
