I don't like either but here are the policies I like:
Medicare for all.
Legalize drugs or at minimum weed.
Cancel Student debt and make college free.
Shift the tax burden to the rich elite and huge corporations and off middle class workers.
Most of those are things Biden's donors aren't gonna go for.
Trump wins, he's going to stack the courts with judges that will prevent any of the above from happening for the next 30 years no matter how any elections go.
If you think sitting at home is somehow going to help any of that stuff happen, that's on you, but I don't think reality bears that out at all.
