I'm looking for a word that describes the behavior of people, or the people themselves, who debate or make arguments, using incorrect or incomplete facts to make their argument. We see it a lot in the world of politics.

An extreme case would be a holocaust denier like Ahmadinejad. But we also see it in more conventional arguments. For example, both sides suggest that people are twisting facts or making up incorrect "facts" on the causes of global warming. When you listen to the extremes of views (whether polar bears are threatened or thriving, for example), we might not know who is right, but clearly someone is wrong.

We're also are having this problem with three new local government representatives in our community. They are twisting or simply lying about documented facts, and make up or twist descriptions of state laws to promote their agenda. Unfortunately it is still effective, because when they introduce something false into a debate, it will influence some of the respresentatives, and even result in a wrong decision when you cannot get the proof of the errors in time to affect the outcome of the debate.

Is there a good word to describe this, other than just the usual fodder like "misrepresenting the facts?"
