Live in a red state? Tell all of your liberal friends to vote PSL!
The only reason not to do so is the vanishingly rare chance that democrats turn a red state, which is basically the exact same argument they use to tell people to vote blue no matter who, but more compelling because it's not typical genocidal am*rican politicians they're voting for.
What are they going to do? Tell you they want to vote for a war criminal on principle? The positive political pressure of having a somewhat popular socialist party far outweighs the small chance democrats could have won (and this is even from their perspective, that the democrats winning would fix everything somehow)
(PA voter. The state everyone keeps sucking off saying we might as well be the only state voting. I was gonna just not vote, but writing in PSL might piss off libs more, so, might do that)
They have automatic write-in access in Alabama, New Hampshire, Oregon, Pennsylvania, and Wyoming. Registering is specifically for ballot access in states with automatic write-in access. So my assumption with them being removed from ballot access proper by the (anti-)Democratic bourgeois party's superPAC lawyers, is that they now can only be written in and can't be chosen directly on the ballot. Assuming the ballots aren't reprinted because it's so close to the election, you would presumably void your vote by choosing them on the proper upper ballot (which they've been "removed" from) vs writing them as a write-in where candidates have automatic access. This is my assumption. Certainly, granted, it would be totally asinine for them to have it pan out this way --- but also US bourgeois democracy is totally asinine, and that's the info I have.
I wrote above, afaik they should still count as valid write ins bc there's automatic write-in access in the state, unlike Georgia where they were fought off the ballot by the (anti-)Democratic bourgeois party's high-finance lawyers, which requires specific write-in registration (for which the deadline has passed). They're just not valid as ballot choices in the state anymore. But it should allow write-ins as far as I can tell because it's an automatic write-in access state per the Election Assistance Commission source I linked --- just can't choose them directly on ballot (even if they are still listed bc it's too close to election to reprint. That would probably spoil ballot).
I do hope they get properly counted though. It would be funny to hear the libs melting down if like 1000 PA voters write in PSL and the news channels show it at the very bottom. Then Harris loses by like 900 votes.
