Immigration and made-up stuff

There are all sorts of myths about the negative effects of immigration.  Now the discussion about Arizona has moved from myths to consistent lying.  I already wrote about how Jan Brewer says all sorts of things that simply are not true, and Matthew Yglesias points to more examples: "The upshot of all this is to create a toxic cycle of misinformation."

This may well be the most exasperating part of debating immigration, because the issue is complex enough without high-level elected officials lying about it (or being so ignorant as to spread untruths because they do not know the truth and cannot be bothered with it).
