Still months to go until the election, if this happened immediately before it then I'd say he's a shoe in, but there is time for it to calm down before the election happens.
There's no way the republicans let this go! They will be ramping it up like you've never seen. They've even started saying that Biden has incited this attack with his language recently.
I might drop off social media until after the election, it's going to be an untenable few months.
