The approval rating of a president almost always drops after they enter office. The reason for this is all of the low information voters that thought their candidate was superman quickly realize that the president isn't going to/can't come through with all of the campaign promises they made. Most people are too ignorant to understand how our government works, and that just because a president says he will do something, it doesn't mean he can/will do it. All recent presidents/candidates do this now, and I laugh every time. Empty promises and low class smear campaigns to manipulate the hordes of ignorant voters.
