Since 7 a.m., candidates and their supporters are working to get you to vote for them up to the last minute.
At Grand Bland High School, there's a blue line that separates the candidates from the voters.
In front of it is what's commonly known as "the gauntlet."
Art Reyes, 51st congressional district candidate, says "There are so many people that converge on them, and you can kind of see the look on their face like, Whoa!"
Webster defines gauntlet as "a double file of men facing each other and armed with clubs or other weapons with which to strike at an individual who is made to run between them."
At Grand Blanc High School, it doesn't exactly live up to its name. No weapons are shown, just candidates and supporters armed with literature.
"I've been doing it for so long," says Jim Lane passing out candidate cards. He wonders how effective his technique is. "It's hard to read these people. They won't tell you the truth."
Others say, it's difficult to sway the majority.
Pia Jesse is campaigning for Linda Kingston for state representative. She says, "They are very well set, either yes or no."
From Kupiec to Kingston, Slezak to Zelenko, they battle the heat and humidity. Fifth congressional candidate Rick Wilson decided to go without the tie. Wilson says, "I'm very happy to be comfortable in this weather, as comfortable as you can get."
"Gauntlet" participants say most people will engage in conversation but will never know if it swayed their vote.
Michigan law says campaigners must be 100 feet away from any doorway of the voting location.
