Congress continues to write laws because the future brings things the founding fathers never dreamed of. Like Cell phones, computers amd drugs being transported across the boarder from halfway round the wourld.
In general the Feds do all right with drug enforcemnt. You might enjoy this.

So you believe the Constitution is a LIVING document, like Dumbocrat congresscritter Ellen Taucher's old blue dress that she outgrew? Is that it? Are you a dumbocrat in disguise?
There is a mechanism built into it to make changes if they are needed. But you think that Congress, the President and the Courts can make the Constitution mean whatever they want to? Is that it? Because they are wiping their asses with the Constitution daily and idiots like you cheer them on.
