The GOP is what it is. If it gets too far out of touch with a good-sized proportion of its members, it will lose elections. As long as it wins elections, it will feel reaffirmed and do whatever it thinks best.
That's reality. The drift towards the center has been fairly slow and has gone unnoticed by many Republicans. That seems to be ending. There's a lot of dissatisfaction going around these days. Will it cause the GOP to lose control of the Congress? I don't know.
If it does, there will be a retrenching of the party. If it retains power, the drift may continue. We'll know more in a couple of weeks. The polls right now are useless in figuring out what will happen.
Me? I just keep voting my conscience, as I have always done. Sometimes you win...
I had enormous respect for Barry Goldwater, and worked, as a young guy, on his campaign. He lost miserably. He was too far to the right for the electorate, apparently, even though he was a great thinker on many issues. The beginning of the centrist shift happened after that, and continues to this day.
I think that Conservatives need to be cautious not to create another Barry Goldwater candidacy. That, I believe, would set the party back for another 20 years or so. Somehow, the shift needs to be more subtle, but the direction is going to have to change, from a move toward the center, to movement in the other direction.
Again, this will be a telling election.
