Misleading Headline?

Here's the kind of thing that makes you wonder about the press these days. Makes me wonder, anyway. This AP news story is headlined, "Poll shows Sen. Santorum's popularity not hurt by remarks about gays." From that, a reasonable person would assume that his popularity rating is right about where it was before he made his controversial remarks.

But in the third paragraph of the report comes this revelation about the poll…

However, Santorum's remarks may have turned some undecided voters against him. His disapproval rating rose from 20 percent in April to 33 percent in May while the proportion of undecided voters fell by a similar amount, from 24 percent to 12 percent.

In other words, his disapproval rating has risen from 20 percent to 33 percent…but his popularity has not been hurt.
