The Politico is reporting that 7 Ohio Democratic Party superdelegates are withholding their votes for Barack Obama and Hillary Clinton until the candidates agree to a "laundry list" of demands on trade.

The group includes Sen. Sherrod Brown, Rep. Dennis J. Kucinich, Rep. Marcy Kaptur, Rep. Tim Ryan, Rep. Zack Space, Rep. Betty S. Sutton, and Rep. Charlie Wilson.

The Politico's Josephine Hearn, Amie Parnes, and Josh Kraushaar report:

The apparent deal among Ohioans is the first evidence of superdelegates’ banding together and seeking concessions from the presidential candidates in return for votes at the convention.
...

"We have a laundry list of measures we think would be effective, some involving tax policy, some involving investment policy, intellectual property incentives to hold investments in this country," [Rep.] Kaptur said.

"I’m hoping superdelegates [who] are uncommitted that have the economy as their major concern will gravitate to our group and use that power to gain additional attention."... "We had a general agreement," Kucinich said of the pact. “We have economic issues that need to be addressed. Ohio has economic issues more urgent than any other state."

Rep. Ryan denies there has been any agreement between the Ohio superdelegates, but told The Politico: "There’s always talk of trying to build coalitions."
