CORRECTED TO INCLUDE EARLY VOTING NUMBERS
According to data from the Columbia County Board of Elections, turnout seems somewhat light as of 4:30 pm on Election Day. Total turnout is a little over 11,600. Normally, one would expect a flood of voters once people get out of work—and no doubt the total will still increase substantially, though probably less than back in the day before early voting.
In the table below, this site has aggregated voters in traditionally right-leaning parties, left-leaning parties, and unaffiliated or independent parties. The tallies do not include absentee voters and their affiliations, but those tend to skew leftward.
