Mainstream dems: fail to pass any significant legislation with the presidency, a tie-breaker in the Senate, a majority in Congress, and a progressive wing willing to compromise on virtually every major policy issue.
Mainstream dems upon losing subsequent elections: How could progressives do this to us?
Perhaps those mainstream Dems, or whatever is left of them aren't wrong to blame those seeking to hold legislation hostage because they want their entire wish list while we're in the middle of an inflation crunch the likes of which we haven't seen in about 13 or so years while arguing that its already paid for.
Looking forward to R's taking both branches of congress in 2022
Don't fret. If 2016-2018 taught me anything it's that Republicans with a majority house, senate, occupation of the executive branch and a receptive SCOTUS could
still freak up a cup of coffee. They're like the old Joker line about a dog chasing a car, once they got it they don't know what to do with it. You'll see a lot of fraudulent actors exposed in terms of running on doing this or that, being in the position of doing so and then going "lol nah I'm not going to do that."
