Not saying there wasn't a spike in people searching if Biden dropped out, but a spike of approx 100 searches isn't really that significant.
Similarly, I looked at the "can I change my vote" trend that I've seen reported, and again it was 1000 searches (if you're generous) and was pretty much entirely on election day. Which to me would indicate was more people who voted early wondering if they could change their vote on election day.
Don't get me wrong, I would love if there was something to blame to make me feel better about sharing a democracy with a bunch of hateful morons, but even trying to find evidence to convince myself that they are more dumb/uninformed than hateful isn't turning up much.
Viva la what he said!
