Increased voting by mail and early-voting means they are consolidating precincts and locations. Consolidating locations saves them money too since they have to pay rent and pay poll-workers. People are getting moved everywhere. We are going through the same thing down here.
Hamilton County has gone from 1000 to 800 to 600 precincts in the past 3-4 years.
The changes in locations, the changes in voting equipment, etc, are causing a lot of turnover in poll-workers too. The competence is definitely down here from what it used to be.
While I live in a GOP area and about 1/3 of our voters got moved, I know that some people in the heavy D areas are getting moved, too. A local TV station, whichever one serves WLW-AM, went to Ault Park to interview voters, as is their custom, and, well, it's no longer a polling place.
But the thing is the old location is still open for other precincts. The workers, machines, etc are still there.
Of course this could be just gvt ineptitude rather than anything more nefarious. But the way things are around here these days, one wonders...
