Well, no. There's no Constitutional requirement for a person not to a lying, cheating, thief, in order to be eligible to the office of President. Would have been a bunch of them disqualified on those grounds. :) LBJ for certain, but many others too.
Of course if the "lying cheating, thief, business had come out before the election(s), then the people could have decided for themselves if it was a disqualification by their standards.
