I think, as an institution, the GOP isn't really about anything anymore. They have lost their way. I've been on this site for a decade, and for much of that there have been political threads with the defenders of the "conservatism," "family values," "personal responsibility," "piety" and being "the grown ups in the room." I have consistently argued that they are none of those things. Trump is the vessel that has revealed how full of shit the whole party is, and how all of their cherished principles were so much bullshit. Almost all of the top Republicans have fallen in line like lemmings behind a none conservative, twice divorced, thin skinned, blowhard, lacking a moral compass, and who is currently embroiled in a trial for selling real estate snake oil under his own name to unwitting citizens.
So, to answer your question ... they are idiots, in my view, and their opinion doesn't matter. They clearly can't be trusted to make decisions, judging by the clown parade of candidates they have put forward over the past couple of decades -- W, who absolutely wrecked the economy and got us involved in two wars? "Bomb everyone John McCain and the Princess of Stupid? Mitt 47% Romney? Yet, once again they were duped -- this time by the world's most arrogant used car salesmen.
And, just like the customers who buy a lemon from a sleazy prick on the used car lot, they are coming to realize the vehicle they thought was going to get them from A to B, isn't dependable and is probably going to leave them stranded. So, there is still some hope for the Republican Party. It's never too late for retribution.
In my view, there is no way that's coming during this election. They will not be rewarded for abandoning all principles and putting Trump out in front of their party. But they have a chance to wise up. So, will this be the final hard lesson that will help them pull their heads out of their asses, or will they keep making the same mistakes that they continue to make in general elections and policy positions? Because those behaviors make them appear as angry, cynical, obstructionist, science denying, poor hating, corporate whores. Will they finally realize that what is needed in their party isn't a "true conservative" (the excuse in waiting for many when Trump loses) but a little humility and humanity ... a little outreach to people they have traditionally alienated. Their candidates get worse every four years. I can't wait to see what they role out for 2020. Personally, I hope they learn their lesson ... but I'm not going to hold my breath.
