If you own stock in a gun manufacturer you might want thank President Obama:
Sarah and Jim Brady and the Brady Campaign to Prevent Gun Violence with its network of Million Mom March Chapters endorsed Senator Barack Obama for President and Senator Joseph Biden for Vice President today, and urged Americans to vote for them.
From looking at the chart and the date of the Brady Campaign endorsement announcement it’s clear the Brady Campaign causes gun sales.* Lots of gun sales.
*I’m just mocking them. Of course I know correlation does not necessarily mean causation.
