Democratic candidates trying to knock off incumbent Republican senators have lined up to disavow the idea of packing the Supreme Court, raising even more questions about why Joe Biden can’t do the same.

Cal Cunningham (North Carolina), Sara Gideon (Maine), Theresa Greenfield (Iowa), Mark Kelly (Arizona), and Jon Ossoff (Georgia) all confirmed to the Washington Examiner that they would oppose adding more justices to the Supreme Court should they defeat the Republican incumbents in their respective states. They’re joined by Democrat Sen. Gary Peters, who is facing a tough challenge from John James in Michigan.
