If there’s anyone more disdained than Barack Obama at this moment, it’s Nancy Pelosi, who is closed [sic] to the least liked American citizen? [sic]
As BooMan points out, Pelosi may not be popular in absolute terms, but in relative terms she's through the roof:
It's important to remember that all four leaders are unpopular. Pelosi, with a 42%-49% approval rating, only looks good by comparison. Her counterpart, Mr. Boehner, remains roughly as popular as a case of chlamydia (18%-62%). McConnell (18%-64%) is even worse off. And less than a third of respondents (32%) approve of the job Harry Reid is doing.
