Vice President Joe Biden tried to call Republican Sen. Pat Roberts on Election Day in an effort to discuss Biden’s statement that Roberts’ opponent Greg Orman, who has campaigned as an independent, will join Senate Democrats if elected.

Biden made the statement Tuesday morning during an interview with WPLR radio in New Haven, Conn. The vice president expressed confidence that Democrats will hold on to Senate control, saying he believes Democrats will win in Alaska, North Carolina, Georgia and Louisiana. And then this: “I think we have a chance of picking up an independent who will be with us in the state of Kansas.”
