Why Polling Just Doesn't Work for Some Questions.

The poll also showed 55% support continued offshore drilling (30% opposed), though more Democrats opposed drilling (48%) than supported it (34%). 43% said the spill makes them less likely to support drilling, compared with 21% who said it makes them more likely and 36% who said it makes no difference.

21 percent of respondents said the largest oil spill in U.S. history makes them more supportive of offshore oil drilling than they were before the largest oil spill in U.S. history?

This is why traditional polling techniques fall apart and become meaningless when applied to certain issues and questions.
