This national survey of 1,000 U.S. Likely Voters was conducted on July 7-8, 2012 by Rasmussen Reports. The margin of sampling error is +/- 3 percentage points with a 95% level of confidence. Field work for all Rasmussen Reports surveys is conducted by Pulse Opinion Research, LLC . See methodology .

In 1942, the U.S. Supreme Court ruled that the federal government could regulate how much wheat a farmer could grow on his own property for his own use. That ruling dramatically enhanced the power of the federal government by making almost all economic activity subject to federal regulation as “interstate commerce." However, voters today overwhelmingly reject that underlying argument.
