A lot of Democratic "victories" in the age of Trump have occurred more because of reality than because of their action. The blocking of Obamacare Repeal is the best example. The Republicans talked unity on the issue when they were 100% certain that Obama would veto any repeal measure, but there were always a few Republicans in the Senate that knew that their constituents would not approve of repeal; enough of them were benefiting and would be grossly inconvenienced if it were repealed. This wasn't so much something the Democrats did as something reality, itself did.
You can say that there was more unity around saving the AHCA amongst Democrats then there had been, and you would be correct. Since every Democrat in the Senate who was there in 2009 voted for AHCA, it would be lame if one changed their mind. But they didn't; even Manchin (the most likely switcher) Heitkamp, and McCaskill stood firm.
The Democrats' smoothest move was making the deal with Trump to extend the debt ceiling. This was a real victory; the Freedom Caucus loonbags would have no problem voting to starve out the government to get there way, even with a Republican President. (I think Trump, in his heart of heats, knows that the Freedom Caucus folks aren't his friends, but he knows that they're Republicans and the same folks that elected him elected them.) They would be in a better position if they can continue to make deals with Trump on areas where they agree. This, however, doesn't seem to be the inclination of most Democrats; they would rather rant than accomplish.
This is the real problem with "The Resistance"; they are preoccupied with ranting over issues folks that NEED the Democratic Party to assert itself don't care about. Gotcha! issues like Russia, boorish behavior decades ago, etc, that folks repeatedly see as ending up as tempests in teapots. This will be the reason Democrats disappoint in the midterms.
This was said in 2009 with the GOP when they were whining about The War on Christmas and birtherism as "gotchas".
And yet 2010 was a landslide.
The 2010 landslide occurred because of fear and loathing over Obamacare.
There's something to the idea that folks approved ACHA before reading it. Its advocates were unable to dispel the fears about Death Panels and skyrocketing rates, and "the government getting between you and your doctor", not being able to keep your current plan (true in some cases), not being able to keep your doctor (an overrated benefit; how many folks here know the name of the last doctor they saw?).
The minute you go on defense in politics, you're finished. The Democrats went on defense, or ran away from Obamacare. They rammed through an historic healthcare bill, and then some wanted to distance themselves from it, or couldn't defend the "Death Panels" drivel.
