(CNN) -- Democrats have usually conceded the evangelical vote during presidential elections, but Sen. Barack Obama is trying to change that by mobilizing what some call the "Christian left." Sen. Barack Obama is expected to talk about faith-based initiatives during a campaign stop in Ohio on Tuesday. As part of his outreach to evangelical voters, the presumptive Democratic presidential nominee will tour the Eastside Community Ministry in Zanesville, Ohio, on Tuesday and give an address on how he plans to builda "real" partnership between faith-based organizations and the White House if he becomes president. Obama's outreach to evangelical voters has also included private summits with pastors, an effort to reach out to young evangelicals and a fundraiser with the Matthew 25 political action committee. It describes itself as a group of moderate evangelicals, Catholics and Protestants committed to electing the Illinois Democrat president.
