It turns out President Obama is in the minority in thinking that a ban on offshore drilling is a good idea. Seventy-three percent of respondents to a new Bloomberg National Poll said the ban on the kind of activity pursued by BP when the Deepwater Horizon rig sank is unnecessary. Those respondents said the explosion, which has left oil pumping into the Gulf of Mexico for more than 80 days, was a "freak accident." So far the White House has issued two moratoriums on offshore drilling after the first one was overruled by a judge. Only a third of respondents said that they support drilling less than they did before the BP rig sank.
