21% of voters said the spill made them more likely to support offshore drilling. That includes an even split among GOP voters, 28% of whom said the spill made them more likely to support drilling and 28% of whom said the spill made them less likely to support drilling."Just 9%" and "only 13%" may seem an odd way to phrase it, but not when you look at the numbers for other unlikely beliefs.
Few voters buy into Rush Limbaugh's conspiracy theory that environmentalists may have been responsible for the spill in an effort to build support for their agenda. Just 9% of voters say they think environmentalists caused the spill while 22% are unsure and 69% don't believe they had anything to do with it. Even among GOP voters only 13% are buying into the 'the environmentalists' did it frame of mind.
