Texas' election chief says she expects 68 percent of the state's 13.5 million registered voters to cast a ballot in this year's election.
That would mean more than 9 million Texans voting, if her projection is correct.
The estimate includes early voting and voting on Tuesday.
Texas Secretary of State Hope Andrade's turnout prediction is 12 percentage points higher than voter turnout in the 2004 general election.
There was heavy early voting across Texas during the two weeks of early balloting this fall. Early voting concluded Friday.
Polls are open from 7 a.m. to 7 p.m. on Tuesday.
