All the candidates save one are espousing broadly conservative agendas. There are important differences, of course, but they are all, save one, in the ballpark of the conservative movement of the past dozen or so years.
Cruz is emphasizing the "I really mean it" meme and regularly criticizes bipartisan corruption and the Washington cartel. I do not see why this should give anyone the vapors.
The exception to the above, of course, is Don Rickles, who is going to make America great again by insulting his way to victory, and easily solve all our problems because they are caused by stupidity, and he is smart.
I would think Don Rickels would be strong Trump. Does anyone know?
