When was this done .. I know it's not recently. Remember, he was mayor of NYC for quite a few years, and these types of events would have been a normal part of NYC life.
To say he's stupid for doing it .. why? Even if he thought he might be president some day .. what does that have to do with this event ..??
I think you're just looking for something to ridicule him about.
really. So stupid. Ronald Reagan talked to Monkeys when he dressed up...so freaking what.
