At this point, I am going to be putting all effort (and still more money) into GOTV here in Texas.
I am reasonably confident that Biden will win convincingly enough to keep the GOP from making a serious effort to overturn the result (though they will whine, accuse, and conspirafy till hell won’t have it).
He can do this without Texas, but turning Texas blue is a dream of mine, and would be a shattering, perhaps fatal, blow to Republican morale and even to their fundamental world-view. They might finally begin to understand that they are out of touch with most of the human race.
