I know some on the right have claimed the early numbers are good for Republicans - I haven't checked as they always lie, but I imagine Democrats will have an advantage in that vote which is then matched by Republicans on Election Day. My main worry is how many of those mailed in votes are going to disappear. I hope most people, if they can, are voting on the day, but I am not one to make those proclamations as I am voting by mail this year.
It's bad for Trump, good for Senate Republicans. They can claim they are the party of austerity (with various outlets like NYT already pushing stuff about the deficit again), crash the economy, and blame Biden for it if he wins, setting up a comeback narrative in 2022. I just hope Democrats can win the Senate because if they don't then Republicans will do nothing, other than investigate Hunter and wait for the clock to run out.
