Saying it was pointless winning the election is not thinking the whole thing through very well. Yes, repealing and replacing Obamacare, which was a campaign promise of every GOP candidate in one way or another, is not going very well. Does anyone think it would have gone any smoother with any of the other candidates? I think we would be in the same quagmire, if Cruise, Rubio, or any of the others had one. I don't think funding a "border wall" will go any easier, and frankly I never did think what was proposed was achievable or affordable.
Rather than looking at what we did not get out of this election, lets look at what we got so far. A SCOTUS appointee. That would have been Hillary picking a person - remember that. With a few exceptions, his cabinet appointments have been positive. Also Tax reform, the Pipeline, and offshore drilling can be through in with many other small victories.
I didn't vote for him, and I still find him rather obnoxious - but he's our President and there is no going back.
If the problem were just the potus, well, that'd be one guy and easily enough remedied next time.
Unfortunately, it is not so much the problem as the GOP in Congress, and then not all of them. You see, in some districts Republican or Democrat is just a brand, like Coke, Pepsi, or RC Cola. No matter what you vote for, the flavor is basically the same (only subtle differences in sweetness and aftertaste).
Those districts want a middle of the road Liberal, a JFK, not a Barry Goldwater to represent them in Congress. They want someone who will bring home the bacon, first and foremost, and get that Gubmint money in their home district, keep the navy base open even if it is a thousand miles from open water, pave the streets with grants, and give folks a lot of fat phony baloney obs to choose from. They don't so much give a diddley damn about politics, about the Constitution, rights in general, balance of power, States' Rights or any of it so long as the show is good, the bread is piping hot, and they get to ride the elephant during intermission.
Now, in the districts which still have voters who care about the things I have named above, not so much including 'higher education grants' or base closures, or even paving the roads, people want someone who will be a regular Mr. Smith in Washington, and vote for that, but Mr. Smith can't get sh*t done because other people who are supposedly aligned with his brand aren't in fact aligned with anything but getting reelected, rolling the pork barrel home, and lining their pockets, directly or indirectly.
And that's why we're in the mess we're in. The Democrats embrace the liberal agenda, which their voters support, and vote en bloc. The Republicans come in more flavors than Ben and Jerry's and have a new one every month.
