Well, I'm not sure that another 4 years will not end the US as we know it simply because we've evolved from what the Founders intended as a Republic with three coequal branches to a "unitary president" who wields power reserved for the to the two. And that's not all Trump's fault, but he and Barr are expanding it.
but the dems just didn't have the courage to confront Bernie. No one wins the primaries without the Southern Blacks. So to win, you have to be black or a white southerner who can appeal to blacks. Bernie is neither, and he could not win a nomination, but the dems feared alienating his supporters. And I'm not sure those folks actually will ever vote dem in a November election.
Maybe a white governor of a state like Ca or Ill could win a nomination if he was popular with blacks in his/her state. NY, maybe, but if it weren't for Trump, Cuomo would look real ethnic. LOL
The pooling of power within the presedency is a problem, I agree, but I don't see trump as any better or worse than any other presedent out there. Hell, Obama was actually far worse in that catagory IMHO and is one of the reasons why Trump has managed to do so much damage. Obama operating from the pen rather than Congress allowed Trump to undo all sorts of things that Obama did by fiat. When given the true oppertunity to take serious power during this outbreak he has largely backed off even with the democrats calling for him to essentially act like a dictator. Trump, for the most part, just wants to take a picture rather than actually weild power. Power takes work.
As for what a democrat needs to win, not sure that race really matters tbh. Sure, you can drive out larger numbers of black voters in the south but the singular focus on that sliver of the voting population in the democratic party is nonsensical to me. The Obama effect was a one time deal because of the historic change that moment represented. People would vote for Obama that never voted before, never will again and do so without knowing a single position or vote Obama ever made. I don't see that happeneing again untill we have a viable female candidate. Black voters are going democrat no matter what anyway until the Republicans can figure out where they went so wrong with their minority messaging and that is not even on the horizon at this point. I see most of the candidates alienating 80% of the nation in a bid to attract 12% that are already with them - it is crazy. I think almost every single contender on that stage was all about reparations during the primary, a policy position almost universally rejected and one that is universally rejected any time an actual proposition is made. You had Harris actually try and charge Biden, of all people, as racist. It was truly crazy.
I think that the democrat party simply needs to purge the Sanders block from the party, period. They are corrosive and destructive to the party as a whole. There is a reason that Trump has tried so hard to make AOC the face people think of when someone says democrat - she and Sanders represent a tiny slice of the voting block that the majority of the US outright rejects. They make really easy targets. It's not like they are going to come out in droves for Biden or any reasonable candidate no matter what they say or do and it is also not likely they are going to vote for a republican under any circumstances.
The right has the same problem. The white supremacists are a blood sucking tick on the Republican's ass they just refuse to squash out of fear of losing votes. IMHO, both parties are loosing many more people by giving the fringe idiots a nod. At least the democrats did not let their populist guide the entire party.
