Left and center split the vote, far right wins.
Left, liberals, centrists, and moderate conservatives ease the path for whichever of them has a better chance against the far right, the far right loses.
We've seen evidence of that for a century, from Weimar Germany through France today.
We should absolutely vote tactically against the far right whenever possible—last week I was recommending it against Badenoch—but we must normalize the idea of reforming our electoral systems, too. Two round systems are better than FPTP but are halfway measures.
