Only in USA, the rest of the world doesn't see lawyers flock to politics. It seems more like there is some corruption that makes lawyers mingle so much with politicians and they scratch each others backs, otherwise why would it be so much more lawyers in politics in USA than any other country?
People hate lawyers, they wouldn't vote on them if they didn't have to, but when the parties mostly show you lawyers to vote for then people don't have much of a choice. In the rest of the world were they do have that choice lawyers doesn't get voted in that much.
