Yeah, and oil fuels terrorism, so lets just ban that too.
We already have laws against trafficking and slavery, and we cant police the world (well, some big military conservatives and big environment liberals think we can).
Starve the beast indeed, remove power from the federal government.
Not an apples-to-apples comparison; and not really even true. Terrorism would find a different lousy excuse if there were no such thing as oil.
We already had laws against terrorism, but 9-11 happened anyway. Just because we have laws doesn't mean anything's being done to substantively enforce them. That's the point Santorum is driving at, here; a point the Obama administration -- and even the Bush administration before him (think :illegal immigration) -- is unwilling to admit.
NOBODY has to expand government to quash porn or terrorism; SOMEBODY has to enforce existing law. THAT is what Santorum is committing to do, for a change.
