Now, now, dare not question the wisdom of a Republican. For that's who helped get it through. Giddy Dolt, our fine upstanding big government, power hungry Senator now, back when she worked in the Reagan administration came up with this 'wonderful' idea. As Secretary of Transportation she thought it would be a good idea to tie federal funding for roads to such a law. If a state passed the law, they got money, if not well their roads went to pot. Want to guess how many states passed seat belt legislation? BTW, you can also thank her for pushing to maintain speed limits at 55 nationwide, helping pass legislation for airbags and those third brake lights all cars have to have now
The same way they can pass a law that says you get treated at an ER even if you don't have money. The nanny state can make the rules if the people want the nanny state.
