Especially in this day and age after 9/11, it would not be beneficial to one's health wishing ill will against the President or any other elected official or candidate under the protection of the Secret Service... lest you get a midnight visit from a pair of trench-coated men (or women) wanting to answer questions at the police station!
I'm of the belief that you should "respect the office, not the person." Considering the way public opinion polls are going, I would not be surprised if The Shrub becomes a one-term chump like his daddy. Unless he makes a major turnaround between now and Election Day. It's all up in the air for now.
