More than 128,000 ballots have been issued in Benton and Franklin counties for today's general election.
They must be postmarked by today to count. Voters also can use secure ballot drop boxes set up in their county -- an option that election officials described as the safest at this point in the election.
"Even if you put it in a mailbox, there is no guarantee it will be postmarked that day," said Stuart Holmes, Benton County's elections administrator. "We don't want anyone to get left out because of a postmark."
The drop boxes are open until 8 p.m. today.
In Benton County, voter turnout is projected to reach 50 percent, while in Franklin County it's on track to hit 40 percent to 45 percent.
Benton County drop boxes are at: the Prosser courthouse, 620 Market St.; the auditor's annexes at 5600 W. Canal Drive in Kennewick and 101 Wellsian Way, Suite E, in Richland; the Benton City, Kennewick and West Richland city halls; and Jefferson Park in Richland.
In Franklin County, drop boxes are at: Franklin Fire District 3, 2108 Road 84, Pasco; the election center at 116 N. Third Ave., Pasco; TRAC, 6600 Burden Blvd., Pasco; the county courthouse at 1016 N. Fourth Ave., Pasco; and the Connell PUD shop, 619 W. Clark St., Connell.
