The state Division of Elections is posting county-by-county early voting totals on its website, HERE. As of Wednesday morning, the statewide total was 48,314 early votes — 31,935 in Republican primaries, 13,111 in Democratic primaries.
Officials say turnout is running lower than in 2014, but on par with 2012 and some other years when there were no statewide primaries on the ballot — as the case in 2016.
Excerpt from a Times-Free Press article:
Kerry B. Steelman, the (Hamilton County) administrator of elections, said Tuesday that voting was down the first three days by some 60 percent from 2014 primaries, which included a contested U.S. Senate Republican primary, a hard-fought 3rd Congressional District GOP primary and a number of top county offices.
This cycle, there are no statewide contests and the 3rd Congressional District race is largely uneventful. But there are three contested legislative primaries, as well as contests for property assessor and school board.
…State Election Coordinator Goins said that the 2016 summer pace of voting is comparable to 2012 and 2008, where there was a somewhat similar lack of big statewide primary contests, along with the same absence of top general election contests like mayor and sheriff that typically help drive voter interest.
In August 2008, for example, there were about 206,000 early voters and 11,267 voters casting ballots by mail, collectively accounting for 38.64 percent of the total 562,795 votes cast.
This year, there are areas with some hotly contested races, Goins noted.
“We’re on track to meet that  number or maybe exceed that a little bit,” Goins said, later adding “we’d like a bigger turnout.”
