Bush lied to us. Actually lies are the common device for many politicians. Notice I didn't include every politician in this. I don't think that Dennis Kucinich or Bernie Sanders is lying to us. The government is only as good as those that American voters put in place.

The "facts" used are generally propaganda devices as power moves. Lies are part of the strategy used.

Do you trust corporations more? Would they lie to us?

Actually corporations control a good deal of the government now so that they are
able to lie with impunity.
