How does this relate to politics? Members of legislatures and their staffers will give out their PIN numbers to lobbyists. The lobbyists, watching legislative proceedings from through a window or even on TV, can directly instruct the members how to vote via text messages. No money changes hands, no meeting takes place, no communication is recorded. But lobbying has occurred.
I'm guessing you don't have the PIN numbers for your elected officials' Blackberries. Just sayin'.
