Government, even in its best state, is but a necessary evil; in its worst state, an intolerable one.
-Thomas Paine
To question government, to be suspicious of government, is fundamentally what makes us Americans. The constitution was set up in such a way to limit government. Government stands in opposition to freedom. Because politicians main interest is in the accumulation of power and the more they accrue the less liberty there is for society.
On a personal note I don't care what party a politician is in I don't trust any of them.
