Back in the 1990s when Californian's (overwhelmingly) passed Prop 187, it was ruled unconstitutional by a Federal Court Judge. Now, I was only 29 at the time, and not very politically involved (didn't even vote until I was in my early 20's), so I really wasn't that tuned into Prop 187.

My question now is, what was so unconstitutional about not allowing illegal aliens to have access to free (non-emergency) health care, welfare or schooling? I'd like to know where in the Constitution it states that Americans have to provide these things to people who are in the U.S. illegally.
