A.P. is reporting a poll that shows a 60% approval rating for the president. Later in the article you find out that the pollsters assume 46% of the U.S. population is Democrat, 29% is republican, and 20% can't make up their minds, or slightly better than the faculty of an average college.
In a possibly unrelated story, some 20% of those questioned think Osama Bin Ladin is still alive. This is roughly the same percentage that thinks Elvis is working in the bodega down the street.
