From which ditch they will run their congressional campaigns.
I am not sure it would go quite that far... after all, they may be liars, cheats, bullies, shysters, conmen, and to cap it all... lawyers. But there is a long way to go from that to suggest they can make the leap to the next level of unconscionable evil and become Congressional Politicians.
Oh, damn, showing my jaundiced and cynical side there, making the overly broad generalization that all politicians are scum of the earth whose sole purpose in running for office seems to be to hop on the gravy train of lobbyists' "Campaign Contributions" and line their own pockets at the expense of the electorate and citizenry of the country they are elected to serve :)
An interesting side-question would be to ask how many competent and genuinely honest people would get into politics to do some real good, but are put off or corrupted in the face of the Gravy Train on one side, and world-weary cynics like me, seeing the worst in all politicians and condemning them without personal knowledge, on the other. Not too many, I guess... (but if you think that YOUR congressman/woman is doing a good job, don't just post about it here, send them a letter praising their performance - if enough people do that, so that they get some positivity once in a while, it might help them to make the right choice next time, too.
Oooo look, a Unicorn!!
