Lewis and his fellow activist Ann Becker are a new breed of canvassers going door to door along a sloping street full of modest and mostly well-kept homes in this declining steel town in Butler County. This is the first presidential election since the founding of the Tea Party movement which aims to reduce the size of U.S. government.
The two activists are not beholden to any campaign - some would say they are a rogue force - nor do they mention Republican presidential candidate Mitt Romney by name.
While they differ with former Massachusetts governor Romney on many policies and suspect his conservative credentials, they are working independently to help him win over undecided voters in swing states such as Ohio.
Fiercely opposed to the reelection of Democratic President Barack Obama, conservatives are trying to employ technology they used successfully earlier this year in a recall vote in Wisconsin to help Romney overcome Obama's narrow Ohio lead in the polls.
Conservative group American Majority Action trains volunteers such as Lewis and Becker to target "low-propensity" voters, or people who are not very interested in politics. They use Gravity, a mobile get-out-the-vote app that aims to filter out regular Republican voters and those who have already voted.
"I'm not doing this for Romney or the Republicans," said Chris Littleton, who is training some 50 volunteers to use the app. "I'm doing this because I'm against Obama."
And in the end, that's all they have. I'm against Obama. It doesn't matter what Romney's policies actually are: I'm against Obama, he says.
You should demand more from your ability to vote.
