Voter turnout appears heavier than expected in one of Alabama's most reliably Republican counties in the U.S. Senate election, and officials say they're not just seeing the usual GOP crowd.

Shelby County Probate Judge Jim Fuhrmeister says turnout appears higher than normal among young people and black voters in Tuesday's balloting. That could help Democrat Doug Jones against Republican Roy Moore.

Democrats have a table outside one of the county's largest voting precincts in Helena, and volunteers from the Jones campaign are canvassing neighborhoods in normally Republican areas.

Fuhrmeister says he isn't predicting a Democratic win, but he expects the party to see some results for its efforts.

Shelby County, just south of Birmingham, is one of Alabama's most affluent counties.
