A 98 year old Alzheimers patient, a 40 y/o retard with an IQ of 50, the president of NAMBLA...... all are technically able to be elected President. But the fact that there is no Constitutional bar to such people hardly means they are qualified.
There's the bit of needing to get 51% of the vote.
Uh,...NO. If that were the case, we would never have had Clinton twice. You merely need to get a MAJORITY of votes in the Electoral College. In most elections, the true popular vote is not even determined...
