Republicans set the stage for sure. That's why I don't understand why Dems are trying to outdo them, having seen all the bs going on for 8 years. Why not do better? Why act worse?
Personally, I don't think it started with Obama, but Bush before him. Obama just kept peeling the scab of wounds that might have healed.
I don't agree that Democrats are acting worse.
They tried to get together with Trump and pass some legislation that both sides could say gave them something of value. They even agreed to a sizeable chunk of money to go to Trump's wall. But a couple of far right congressmen blocked the compromise I was thinking of, and Trump flopped on something he had previously agreed to, and tossed in some horrible xenophobic language to boot.
Republicans didn't give Obama nearly that much of an opening to get something done. Trump keeps bringing people to the table and acting like he's willing to play and then tossing all the cards into the air.
Meanwhile Republicans are doubling down on the things they accused Democrats of during the Obama years, such as rushing legislation through before having time to read it, legislation which didn't even had time to be proofread and retyped, and without accepting input from the opposition. Where the Democrats spent months and were accused of not giving people time to read the bill, Republicans spent days, sometimes with less than a dozen contributors in closed door meetings, and literally did not give the rest of their caucus time to read the legislation they were supposed to be voting on.
There's going to be some resistance no matter what. Politicians have to support their ideals and posture for their constituents. But Democrats were willing to work with Trump on some of the promises he made, and Republicans played spoiler for their own legislation.
It didn't help that the GOP legislation was so bad that even Trump called some of it "mean" in between calling the same legislation "wonderful".
That was last year -- when Trump was so desperate for Obamacare legislation he would have signed anything.
On the matter of immigration, GOP lawmakers are afraid to pass a bill because they can't take Trump's word on what he has said he will sign, and they don't want to be on record having voted for any compromises which can be used against them in primaries, with potentially Trump being one of the people who would use the vote against them even though the day before the vote he had told them to make the vote and he would sign it.
Short version: Democrats have tried to work with Trump but Republicans blocked it. And Trump is so mercurial that now Republicans are afraid to even schedule a vote on legislation because they don't know if he'll sign things he said he would sign.
