The most common reason people keep giving for voting Biden is “not trump”. And lots of people don’t like trump, but will never vote for any Dem.
If there’s literally any other options, it’s easier for someone to pick one rather than leave it blank or write in a name.
2020 was insanely close and decided by a handful of states.
It’s a weird situation where for most people their state is decided before the first vote is cast, where other states it could come down to 4 digit votes.
So things that seem like they’d have no effect, can actually be huge.
Like, RFK can cost Biden 10% in Cali, and it doesn’t matter at all. But if he costs 0.1% in Michigan it could change the election.
We need to switch to popular vote for president, but it’ll probably never happen. Until then random stupid shit like rfk can decide elections
