John Hinderaker of Powerline writes about the collapse of faith by Americans that the Federal government reflects Jeffersonian principles.
I think the more significant cause, however, is the general one--a growing conviction that America is governed by a political class that has its own agenda, involving its own enrichment as well as the endless expansion of its own power, and that this political class is contemptuous of the opinions of ordinary Americans and is determined to impose its will regardless of how Americans vote. I think this perception is in fact true.
Folks at the American Spectator agree.
