Texas is a politically schizophrenic state; it's a historically liberal dixiecrat state that thinks it's a red state. The LBJ and Bush dynasty liberals along with the illegal importing ag-lobby and “minimum wages should equal indentured servitude” crowd still rule over texas. They are basically a miniature version of mexico, complete with an oligarchy rule.
So who cares if a texas city has a lesbian mayor, as long as their leader “capt. hairspray” perry keeps that border wide open, and jumps to Neito's every whim.
