David Frum has an excerpt of his recent column on why Americans think all politicians fail them, but I think he overlooks--at least from the part that I can read--the role that his own party has played in this. After several decades now of demonizing government, why would he think that the public would somehow trust their representatives in that government?
In fact, there seems to be this scenario going on--since Watergate. Republicans tell the public that government and politicians are evil and can't be trusted. Republicans then win elections on that claim, then take steps to prove that government is destructive and harmful to the public. Then blames Democrats for their own failings.
Rinse and repeat.
