Honestly, from the lowest level to the tip top, I trust no level of government to have our best interest at heart these days. Politicians, for the most part, have their personal interests at heart. Politicians are like lawyers - 99% of them give the rest a bad name (that's a joke - the number isn't quite 99% ). Many other folks in positions of authority (including some who do the same job I do) will use their job for personal gain in some form or fashion. It's not everyone by any means, but overall - I do not hold much faith. It's sad, I know, but it's our world as I see it.
However, the level I distrust the most resides at the federal level. We were given a nice layout of how this whole country thing was supposed to work when our country was first formed. Since then, it has been twisted and distorted so much that it disgusts me.
