Well, I didn't see this coming, but I don't see Trump as the problem here. The GOP leadership might try to shove this off on Trump, or even "nevertrumpers" but that isn't what the 2018 election will be about.
It will be about the rank failure of the GOP to repeal the ACA, to build the wall, and to secure the borders, to remove the penalties of the ACA, among a host of other promises made and not delivered on.
People who are increasingly under pressure to perform in jobs (if they still have them) are going to look at the Grand Old Party's nonfeasance after a decade of providing what the Party needed to fulfill its promises and say "You're fired!"
Many out here in the real world, away from the ivory cloisters of the halls of power have been hanging on by the skin of our teeth, lost wages, business, businesses, and jobs--not to mention health care policies which were adequate for our needs but were eliminated by the tender mercies of the ACA leaving us paying multiples for worse insurance--and waiting for the do-nothing party to get something done about the policies which have wrought destruction on the Middle Class.
It. Ain't. Happening.
They are too busy attacking those among their ranks who aren't swamp dwellers and busy waving excuses for them to fulfill those promises made to TEA party folks who put many of them in office (or at least cast the deciding bloc of ballots).
Well, that support will be lukewarm at best, because instead of being ready to use the power they were given, they've acted like a couple of rutting deer in the headlights, busy fighting over who gets the harem up there in DC instead of doing their job. They came into the session mostly unprepared, and will leave it the same way.
That's in serious contrast to the opposition Liberal Democrats who, when they get control, have the stack ready to stuff the hopper and get more shit done during their first 100 days than an elephant herd with dysentery. Why? Because while the GOP was deciding which pair of sweat socks to put on back in the locker room, the Dems were on the field, in formation with the plays all memorized--and playing for the same team. I don't agree with anything much they do, but I must admire how efficiently they get it done.
While the GOP leadership will try to pump this off on Trump, they know the drill. They know how things work on the Hill. They know what the little people who cast the thousands or even millions of votes which put them in office wanted them to get done when they made that choice, and they promised it to them--Not just not teaching our grade school kids how to have anal sex, but for the Congress to quit practicing it on the electorate and get the Federal Government off our collective back.
If the GOP goes down in an electoral bloodbath, they need to remember, they are the only ones holding the knife. It's sad to say, but here I thought the GOP leaders would be the apex predators of the Swamp. Oops, my bad. Instead we just have the bottom feeders, longing to lurk in the lucrative comfort of the shadows.
They will try to blame Trump, but from what I have seen, he has done what he can with his pen and phone--maybe a bit too much on occasion. The rest is up to Congress.
