I just watched a 6 minute interview of him from mid-February. They talked about healthcare, but never asked about covid, and he never made a single comment about covid.
There were no debate questions on covid around that time. I think the Feb 26 debate had the first covid question asked. Biden said he would do what he did with the Ebola pandemic to keep it coming to our shores...even though he criticized Trump for trying to do exactly that. Not quite the same thing, of course...more deadly, but not as contagious. Otherwise, it was all bluster...he kept getting louder about throwing more money into the CDC.
Meanwhile, right around that time (late Feb.) Deblasio (even his City Health Commissioner) and Pelosi were telling people to go to restaurants, to go to festivals...don't let the covid virus change your life. They were more worried about racism at that time than in saving lives, which is what we would get more of if they control the country...and I think we will get that. So, be at peace; I think you will get your way. I predict things will get better immediately upon his election.
