Miss B - You Canadians are doing it all wrong. If ya want to live in the land of the big PX, you don't have to do all that crap. Just:

(1) Fly to Tijuana.
(2) Walk across the US border, and stay.

If you can convince the Democrats that illegal immigrant Canadians will breed future Democrat voters, and if you can convince the Republicans that you'll work cheap and increase business profits - then both parties will work like hell to make sure you're not sent back to your frozen homeland. Es verdad.

As per the original question - drug testing welfare recipients shouldn't violate any rights, 'cause they don't have to apply for welfare. If you don't want to be tested, don't have your hand out.

Same with driving - people don't HAVE to get a driver's license and insurance because they don't HAVE to drive. But that brings us to the interesting question the Supreme Court is about to decide, the "individual mandate" of health insurance. Can the government force citizens to buy a product from a private companey just because they're alive, and with no way to opt out?

I've got my opinion on that, and it'll be real interesting to see what the Supremes say.
