The numbers in this country are going to continue, unabated, for months to come We won't see widespread results of the vaccine for until enough people have been vaccinated. We already know a shockingly large portion of the country will hesitate to get it. After some of those people see the vaccine is not causing people to grow a second head or a 3rd ball, they'll fall into line, but I would be shocked if half of this country is vaccinated by the end of 2021. It will be autumn before we see the vaccinations having their desired effect in any large scale way.
Anything Biden does will not have an effect on the number of those hospitalized or dying for weeks after he is in office. And by now the genie is so far out of the bottle, his administration's effect will be limited. The time for the federal government's response to be meaningful was in March and April. Or maybe August and September. Not any more. People who won't wear a mask are not going to put one on because Biden asks them to for the next 100 days.
I would be shocked to my bones if there are fewer than 500,000 dead by April 1.
