Arizona Representative John Shadegg has been trying for lo these many years to convince Congress to pass the Enumerated Powers Act into law. Simply put, the measure would require that all bills brought before the House contain a statement citing which specific part of the Constitution authorizes the legislation. For a group of people, each of whom swore an oath to uphold the Constitution, you would think Shadegg's idea would be a no brainer. Instead, the idea hasn't gotten enough co-sponsors to give it a plausible chance.
It might be interesting if congressional candidates were asked about their support for the bill during the course of this summer's town hall meetings and campaign rallies.
