Both are objectively terrible, the Democrats are tepid liberals that are trying to put band-aids on gaping holes in a sinking ship rather than solving the underlying issues.
The GOP is, of course, fascist, and thus far worse, but in the sinking ship that is America, continuing to sink without fixing the underlying issues is bad as well.
Actually fixing the problems is far greater than the DNC, which is far greater than the GOP.
Edit: no, I’m not advocating for third party voting, I plan on voting for Biden, because I believe change must come from below. Begging the DNC to fix the gaping problems with American society will never get anything done, ever. Organize, donate to strike funds, actually try to build pressure from below.
