Delaying a nomination is unpopular in Ohio, where the incumbent Republican already trails.

Democrats predicted almost immediately that the GOP blockade of a new Supreme Court nominee would be a problem for swing state Republicans.

A poll out Wednesday shows they might be right, at least in Ohio...

The new warning sign for Portman comes in the question the survey asked on whether the Senate should "consider a candidate nominated by the president to fill the vacant seat," or "delay action on a Supreme Court nominee until there's a new president."

The poll found that 56 percent of Ohio voters want the Senate to weigh a nominee -- including 58 percent of women and independents. That's against just 41 percent who said they want to delay.
