Both sides are guilty of this, but since most of the media is left leaning, they tend to put themselves on a pedistool and try to show that they have better ethics then the right.
Of course, that isn't so. And [HERE] is an example.
In fact, the left tends to by, IMHO, more corrupt and less ethical then the right.
But, neither right now meet the standard that we need to have a government that is free enough from big interest to make the hard choices that this country needs for its long term prosperity.
