COLUMBUS, Ohio - Another Democrat is entering the race for outgoing U.S. Rep. Pat Tiberi's seat in central Ohio.

John Russell, a 27-year-old Galena farmer who unsuccessfully ran against state Rep. Rick Carfagna last year, said he plans to announce his candidacy for the 12th Congressional District on Saturday.

Russell, a 2012 Cornell University graduate, said he's spoken with the Democratic Congressional Campaign Committee about his candidacy and has lined up a couple of "nationally experienced vendors" for campaign functions such as direct mail, list building, and online fundraising.

"It'll be a narrow path for us, but with momentum, I think we could get the support of national groups and pull off a win," he wrote in a Twitter direct message.

In a release, Russell vowed, if elected, to focus on health-care, campaign finance reform, and Ohio's opioid epidemic.

Russell will be the fourth Democrat to seek the seat, which Tiberi has said he intends to vacate early next year. The other Democrats who have filed include Licking County businessman Ed Albertson, who lost to Tiberi last year; John Peters, a special education teacher in Newark; and Doug Wilson, a health-care professional from Mansfield.

Several Republicans are considering runs as well.
