@mattblaze They've succeeded in generating a little extra chaos and uncertainty, which is the real point. The fact that SCOTUS failed to put the kibosh on this immediately is a Trump victory by itself.
Same with: they don't need to actually deploy ICE to polling places, they just need people to think it might happen, in order to change voting behavior.
You don't need me to tell you this but it needs to be said: Elections are won or lost in the margins.
