The other reason the US is seeing a surge is because Democrats have been protesting in large groups on the streets for weeks now. They are young, so they won't die, hence why you don't see death rates going up.
Even mayor Garcetti now admits protestors are spreading the virus.
The most damaging events haven't yet happened to Biden. The media has dealt with kid gloves over Biden, even though he's been implicated with the Epstein case - there are victims with testimony against him, his son and himself have been implicated in Russia and China making business deals, he himself has been implicated spying on the Trump campaign.
He's just cancelled all his events and probably looking to cancel any debates, putting pressure on University of Michigan to cancel the debate and not wanting to do any replacement debate - that's right, instead of the typical 3 and not agreeing to the format of 4 debates the Democrats do themselves, we'll see 2. Watch and see, all the other debates will slowly get cancelled either by the Universities or by the Biden campaign.
