IMHO there are only two candidates that will not stay with the status quo of the GOPe. They are Trump and Cruz. Carson is self destructing with his support of TPP and Puerto Rico statehood. For me it is either Trump or Cruz or better yet a Trump/Cruz ticket.
Well, then the only ones left to worry about is this greasy bunch...
