The other day, House Minority Leader Nancy Pelosi nonchalantly explained to a group in Florida that conservatives are in the "E. coli club."
The next day, a pro-Barack Obama super PAC began running an ad blaming Mitt Romney and Bain Capital for the death of a steelworker's wife (who actually had insurance and passed away seven years after Romney ran Bain and five years after her husband was laid off from a money-losing steel plant).
The Obama campaign has, more than once, implied that Romney is a felon.
