Don't forget that it's not ok to vote for your candidate because they don't already have enough support, therefore there's no way to ever reach the threshold where it'll be ok to vote for them.
It's only ok to vote for the neolibs that the billionaires approve after a promise that nothing's really going to change.
Even in a state that's so blue the Dems have no chance of losing, voting for or writing in someone left of the incumbent will still be deemed a vote for the red team.
