Republicans are on offense for two Ohio seats currently held by Democrats, but trouble in Miller’s seat could leave fewer resources for the pickup opportunities.

In a sign he may be bracing for a competitive race, Miller, in an interview with CNN, brandished his bipartisan credentials, highlighting support for two issues that might appeal to Democrats.
