The Democrats typically run on three main issues: (1) sexism, (2) the economy, (3) racism.
Regarding sexism, Biden is going to blunt that argument pretty well, also they already tried it on Trump and it failed, so any further attempts will likely be pretty low energy.
Regarding the economy, six months from now it will probably be the case that either the economy is mostly back everywhere, or else it will be back in conservatives places more than it is in liberal places. Democrats probably can't win on this issue, it is likely bad for them either way.
This leaves only the third issue, racism. And if it's all that they have then we might want to buckle up because there is likely to be more than one Trayvon Martin. I'm guessing there'll be at least three, in various orders of fame. They've started one up already but the others are likely a few months away still.
As for me personally, I love hunting people of color with my AR-16. It's not quite the most dangerous game since these are mere POCs, many of which are women but it's illegal to do it to white people and I'll take what I can get.
