New York City Mayor Michael Bloomberg hit all three active presidential candidates for their inability to stand up to special interests all the time. "All three are senators. I think if you look at their voting records, all three have shown instances where they have stood up to special interests and, sadly, all three have also signed on to a lot of these special-interest bills,' the mayor said, though he did not provide any specific examples."

"Mayor Bloomberg delivered his evaluation at a news conference that followed his keynote address at the World Science Summit, a gathering of scientists, academics, entrepreneurs and government officials at Columbia University. In the address, he challenged Congress to lift all tariffs on biofuels like sugar-based ethanol, which he said is cheaper to produce and generates less carbon dioxide than the corn-based ethanol made in the United States."
