Frankly while I am still baffled that someone like Trump was put in the White House I am also very baffled that Biden was the best candidate that the democrats chose to represent them for the elections.
It really says something about the state the parties are right now.
With the democrats, you're not really voting for Biden, you're voting for the "core" of the party itself to run things, Biden being the medium through which things will be ran. More than likely Clintons-Obama regimes should have heavy influence there.
With the republicans, it's a mix up of voting for Trump himself and the republican party. The party itself doesn't see Trump as it's ideal candidate, which makes him even more appealing to people who're fed up with both parties.
The other issue Trump created is in the image of the republican party and taking away democrats because of his progressiveness that's pretty close to the democrats. Trump prior to becoming president was a huge supporter of lgbtq shit, contributed a lot to inner-cities, and helping out minorities. For fucks sake Opera was buddy-buddy with him up until election year.
Trump was/is the anti-establishment. Biden is the establishment. The republican party don't want Trump as the president, but they have no choice lol. The Democrat party do actually want Biden to be the president.
