It didn’t turn out well, of course. Mayor Jameson spent too much time obsession on Spider-Man and not enough time fixing the subways. That shouldn’t have taken anyone by surprise. New Yorkers knew what they were getting when they voted for him but they elected him anyway.
As mayor, Jameson ended up getting manipulated by both Doctor Octopus and the Green Goblin. It’s no wonder that Mayor Jameson failed to even finish his first term before having to resign.
He was still better than de Blasio, though.
