Been working as a registrar at the early voting polls. It's a boring job. There are five of us and enough work for .25 of a person. So I've been assigned to guiding people into the building (even with the signs it can be tricky, I'm sure some architect won a design award for this stupid government building we're in, but I digress.)
The first half of my job is basically to point people toward the correct entrance and then directions to the correct room to vote. The 2nd half is to thank them for voting as they leave.
I say nothing political or anything about candidates. Just directions and "Thanks for voting" (or a slight variation, like "Thanks for coming to vote today.")
African-Americans like to say that they are/have voted for Trump/against Hillary. Several people who I would have pegged as Trump supporters have stated they have/will vote for Hillary to stop Trump. Very, very, few young people are early voting. In 2008 and 2012, young people (under 25-ish) were the vast majority of early voters. No so this time. It's mostly elderly and middle-aged, middle class that flocking to the polls in droves. I can't get a feel for this election, like I have in years past.
Even though my area/city/county is mostly (heavily) red, it did go for Obama in 2008. This year, I really have no feel for how this is going.
And yeah, early turnout is very, very heavy. We have 14 machines, and very frequently there is a line. In years past we only had 8 machines, and there never was a line to wait for one to vote.
