 So it's almost half of the Democrats are saying that. Concern about the age, Biden's 81, Trump is 78, existed before the debate, but it became much worse Thursday night. The president's family encouraged him to stay in the race and keep fighting. Maryland Congressman Jamie Raskin, a Democrat and White House ally, called it a difficult situation on Sunday. He's one of the few. Again, that's the worst that they've said is we've got to be concerned.
