I agree.
There's a whole host of incumbents I suspect are alcoholic, dishonest, lazy and too power hungry to be in office, but voters continue to reelect these people even after their problems or shady dealings have been exposed.
Patrick Kennedy will undoubtedly be reelected, and Duke Cunningham won reelection several times after scandals had emerged about him. It took a trial and a conviction to get him out of office and I liked him, but knew he was a heavy drinker for many years even though I didn't live in his district.
It seems a conviction is necessary to get them out of ooice. I can cite others too --- Dan Rostenkowski; Jim (beam me up Scotty) with the long surname, and the congressman from IL who messed with a teenage firl. There's others.
We have too many flawed people holding elected office.
