They could ‘wave a magic wand’ and address campaign finance regulation, but the democrats need that structure to run their campaigns.
It's not just (or even mostly) the democrats that need that structure. It's largely republicans who are (ironically) a minority party that need outsized money from a smaller pool of donors. Republicans do not have majoritarian, grass roots support for just about anything they do and rely to an even larger extent upon big money donors. But there also is no magical wand Biden could wave. You need legislation to pass which requires the legislature to act. Democrats have a non-filibuster proof majority in the Senate and a minority in the House...you ain't passing jack shit with those numbers besides perhaps more billions for bombs. I'm surprised they even have a speaker and have funded the government with the state of politics in this country. I almost would've bet money on a default a while back.
Fascist voters are responding to extremely real material conditions; they aren’t going away until those material conditions are addressed.
I don't know if either part of this statement is true. Historically, fascist movements have been defeated in different ways but at least one of them is just killing them in war.
I also don't understand advocating against democrats in the short term even if it means they eventually lose out to fascism because every moment that you aren't under fascism is better than living under it. Delay the inevitable long enough and it is no longer inevitable (see: Trump and the justice system).
Frankly, I find it surprising that there is not a group or person who haven't tried primarying against Republicans from left of the Democratic party position.
The GOP seems like a cult-of-personality shell that is completely moveable on policy (because it doesn't have any except perhaps hating "those people").
That's perhaps because it's all about the $$$ and the leftist groups have found themselves wanting in that area, but ultimately I find it a lot less miserable to live under Republican presidents than Democratic ones, even if it isn't utopia.
And to kind of conclude the earlier discussion, I think we're closer to either a civil war or a blind black jewish lesbian woman amputee winning the presidency than we are to a viable 3rd national party in this country.
