Remember, he didn’t even campaign in 2020...he was in his basement reading old Classified Documents.
What he did do, is constantly ran TV ads at a time people where at home due to the lockdowns, and the Trump campaign never countered the ads.
I don’t watch television myself, but apparently a lot of Americans still do.
He didn’t campaign in 2020 and he’s still here. This year he still has drop boxes and now he has illegals.
