San Diego, California (CNN) -- Oh no, he didn't go there. Even in a political climate where it sometimes appears that anything goes, Bill Richardson crossed the line. When the former New Mexico governor recently attacked Republican Sen. Ted Cruz of Texas, for -- in essence -- not being Hispanic enough, or not being the right kind of Hispanic, Richardson went too far. Way too far. During a web interview after an appearance on ABC News' "This Week," the Democrat was asked about Cruz and said this: "I'm not a fan. I know (Cruz is) sort of the Republican latest flavor. He's articulate. He seems to be charismatic, but I don't like his politics. I think he introduces a measure of incivility in the political process. Insulting people is not the way to go."

Navarrette once played authenticity game, but he says he grew up
I disagree with most of what @placeholder has said about immigration.
And by senior year, when I began to challenge the liberal orthodoxy that many @placeholder worship, I got a taste of my own medicine.
