4) Rep. Tim Ryan for Ohio Senate

Columbus native Morgan Harper, a former adviser for the Consumer Financial Protection Bureau, is challenging moderate Rep. Tim Ryan in the state’s Democratic Senate primary, a race that’s attracting national eyeballs.

Harper’s resume reads a bit like Sen. Elizabeth Warren’s (D-Mass.). A lawyer and policy wonk, but from the Midwest, not Massachusetts.

She hopes that in Ohio, the state that Democrats have watched bleed red to Republicans over the last several cycles, she’s making the pitch that populist policies like Medicare for All and the Green New Deal are needed to inject optimism and concrete results into struggling areas.

Ryan, a Youngstown native and early backer of Biden, has long enjoyed the support of the party’s establishment wing. While some Democrats are skeptical that the seat can go to any candidate from their side of the aisle, Harper would have to outcompete the moderate faction’s favorite candidate in 10-term Ryan to have a shot against the eventual Republican nominee.
