Yup. I was all-in for Cruz until his campaign sent out those mailers in Iowa that told you how your neighbors voted, and told them about your voting habits. That was Big Brother, not "Constitutional conservative."
And when the campaign's response to the outcry about it was, "Hey, everybody does it!", that sealed the deal for me. Bad move, and it all fell apart with crazy Glenn Beck after that.
Cruz supporters cannot process the disconnect between being the evangelical candidate and employing the master of gutter politics, Jeff Roe.
