Sonia Sotomayor, based on reading a few of her opinions and summaries of dozens more, appears to apply the law as strictly and logically as possible. This is of course exactly what the Republicans always claim to want: supreme court justices who will strictly apply the law. It is no surprise that the Republicans have already decided not to attempt a filibuster.
Unfortunately, like all other recent nominees, she seems willing to be a lot more cavalier about the constitution. While she's ardently championed the first amendment in some cases, she's quite willing to dismiss the second amendment as not being "fundamental", even in the face of a recent clear supreme court ruling to the contrary. I guess she's never lived in a country that became a dictatorship.
I wish that one of these years, we'd get a nominee that was willing to strictly interpret the constitution, as well as the law.
Are you talking about the commerce clause, used by the federal government to justify all sorts of laws because 'almost everything is related to commerce', or incorporation, which uses the 14th amendment to apply the bill of rights to the states as well as the federal government?
