Gwinnett has no countywide elections today — but polls are now open in several cities holding local contests.

Polls opened at 7 a.m. and will be open until 7 p.m.

Several Gwinnett cities will elect mayors today. Most mayoral candidates are running unopposed, however, including those Braselton, Dacula, Grayson, Sugar Hill and Norcross — where unopposed candidate Craig Newton will become Gwinnett County's first-ever black mayor.

The lone contested mayoral race will be in Loganville, where former city councilman Rey Martinez — who has a chance to become Gwinnett’s first Latino mayor — is taking on Donna Jones.

Several Gwinnett cities have council seats up for grabs as well.

High interest races include a vote in Peachtree Corners, where incumbent councilwoman Jeanne Aulbach is facing opposition from Joe Sawyer and Luke Crawford.

Crawford drew heavy criticism last month for a series of controversial Facebook posts.

A similar race was shaping up in Suwanee, where incumbent councilwoman Beth Hilscher was expected to face off against challenger Joe Briggs. Briggs was left to defend himself last week after a string of his inflammatory tweets about Jews and Israel was brought to light.

Briggs later dropped out of the race.
