Cruz is being portrayed that way (okay, maybe the personality assessment is accurate, but he is one of the best in the US Senate in terms of both conservatism and character, whether you read the details vote by vote or go to a conservative or Tea Party site that ranks politicians). I would hope that most people would check more objective sources than the opposing campaigns and their operatives.
He stood Carson voters to some extent with a lie in Iowa.
He breached privacy laws to shame people into voting with that flyer with neighbors voting records being mailed for others to see.
His buddy bought rights ton Mrs. Trump photo that was leaked to his PAC in Utah.
He’s making back door deals with the Washington cartel.
He and his wife appear to be Goldmas Sachs proxies.
I could go on and but Ted Cruz IMO isn’t worth my time.
