He made a mistake. One is supposed to like the entire country and he a president for the entire USA even if certain states have a majority of people who don’t support you. You are just Obama but going the opposite direction by being playing up divisions. I too have disliked various areas of the country. But have come to see that good people, for whatever reason, end up or were born in those places. Doing a generic statement can be taken to mean you hate everyone in the area.
Cruz is getting edgy...and he's got a vicious temper.
