@Bliss I don't particularly believe anything much at all about the polls, except not to trust polls.
Getting enough people to the voting booth to vote in the first place, and making sure enough people don't vote without realizing they've been thrown off the rolls, that's where I suspect the work is.
The US has historically been abysmal about getting people to the polls. We have comparatively low voter turnout. To me that feels like opportunity if seized hard enough.
