Ron Olesko said "Songwriters really have nothing to lose. Their "constituents" are different from a politicans. If a songwriter "loses", they have another gig the following night to recover. A politician loses and they need to find other ways to serve."

Sorry Ron, I have to disagree. A songwriter's "next gig" will always depend on his/her last (few) song(s) or performance(s) - otherwise his/her currency starts to go. And a songwriter through the songs puts his/her beliefs and personality out on full display with no excuses. A politician however can always hide behind the party line and many have made spectacular comebacks after one or even more major "losses", whether political or even ethical. I have UK examples in mind - Jack Straw, Prescott, David Blunkett...
