Thanks.
Do you know if the Republicans are posting poll watchers, or reviewing voter rolls?
1) Yes and 2) probably not.
Several years after I moved here and bought a house, the previous owners of the house were still registered voters at my address. I asked the county clerk about this and she said that, unfortunately, state law prohibits clean-up of voter registration rolls. Only the people whose registration is obsolete can delete their registration.
Several years ago there was a big ruckus about this kind of thing. Some out-of-state chapter of Common Cause barged in and blocked the practice of cleaning up voter registrations that were obviously obsolete.
