Dumb-ass Bigot = Conservative Racist Republican Candidate, Conservative Homophobic Representative

The 'N' word used to be common in the deep south; didn't make it any more acceptable than wetback.
Here is a turn of phrase that is so common nationwide that it is as natural as breathing when referring to an especially stupid conservative:
"dumb-ass bigot".
It's a very flexible phrase; you can put the stress or emphasis on any of the three syllables, depending on your region and dialect, and still be correct.
