Absolutely correct. A Senator isn't a Congressman. No way. Terpfen should try going up to a U. S. Senator, then try to persuade the Hon. Sen. that the latter is a Congressman. Our FRiend will be lucky to escape with no more than a tongue lashing!
My sympathy goes out to the poor Senator whose ego I would have bruised by daring to suggest that he serves in the same branch of government as a lowly Representative.
