As candidates hustle for voters' support, interest groups are working to drum up numbers of their own. Martin Torres has been all over Chicago, holding voter registration events.
It's the Latino Policy Forum's goal to sign up 5,000 voters. He says Latinos make up 16-percent of the state's population, but the community's political influence hasn't kept up.
"It's not just our vote, but representing the interest of those who aren't able to vote; many of us have friend and family who are in that position. And so those of us that are in a position to vote, makes it extremely important that we do so."
Torres says the Policy Forum is still registering people using the traditional method: by hand. That way, his group can keep tabs on the newly registered voters, and encourage them to cast a ballot Nov. 4.
For the first time this year, voters can register to vote online. Grace period registration and voting begins Oct. 8, and runs through election day.
