Re:Not blackmail (Score 1)

So would this make lobbying groups extorting from politicians as they use their influence to get what they want?

Not necessarily, for example: Extortion: Vote our way or we'll break your legs. Blackmail: Vote our way or we'll send the photos of you and your secretary in bed to the newspaper. Bribery: Vote our way and we'll contribute to your re-election fund. It's all in how you coerce the politician.
