More than 440,000 voters hit the polls Tuesday in Montgomery County, which would be the highest turnout of the last 16 years, according to preliminary turnout data.
The total of 440,421 is 76.51 percent of the county's registered voters, the county's preliminary report showed.
That percentage, if it holds, would be a slight increase over the 73 percent that voted four years ago in the presidential election between President Barack Obama and Republican challenger Mitt Romney.
Prior to that election, nearly 75 percent of registered voters cast ballots in 2008, 71 percent voted in 2004 and 65 percent voted in 2000, according to county records provided online.

A spokeswoman for the county said the voter statistics for Tuesday's election are not final and will be certified in a process that will begin next week. She said the certification of the results could take several days.
In a town-by-town count, turnout ranged from 82 percent to 63 percent. The top 10 of the county's 62 municipalities was dominated by rural towns and boroughs like Marlborough, Upper Salford and Green Lane. Upper Dublin was the only town with more than 10,000 registered voters that made the top 10.
Municipalities at the bottom of the list were Pottstown and Norristown.
