The United States Senate is an intentionally slow moving body when it comes to passing laws, but the nation's upper legislative chamber is even slower when it comes to catching up with the popular will of the American people. That's especially been on display when it comes to the nation's pot laws, but now there's a growing core group of senators who are vocally crying out for the federal government to catch up with the states, at least when it comes to medical marijuana.
