My reference to Paul being an "old political hack" is just that. He's making a living as a politician. He's a professional politician for which I have a strong distain. I don't think our Founding Fathers visualized a bunch of individuals making a career of politics. Paul's sanity or lack thereof is of no concern of mine.
It's different when you're a Congressman. You can't just serve 2-3 two-year terms and then voluntarily quit. I would rather have Paul in the people's House than serving 20 years in the Senate and be disconnected from the people. Besides, Paul resigned his House seat after he lost to Gramm in the 1984 Senate primaries and returned to medical practice. He then came back in 1997.
He's been in Congress for about 20 years, but has he accepted all the perks that go with it? He's never participated in the Congressional pension or voted for a pay raise.
