Why

So as I sit here at my computer thinking about all the hype about the presidential campaign I wonder why. Why, must all politicians be such hypocritical liars? They say this year is going to be different we arent the childish people you have had run for your presidents before, but yet they do the same thing as their predicessors. They says they are going to be adults about things but yet still act as children do. So why should the American people trust them anymore than they trust our current leader, which facts show they dont. If anyone can answer these questions I would really like them.
