Bad news for the POTUS: an ABC News/Washington Post poll (PDF) Tuesday reveal that Barack Obama will lead off his nomination for a second term with his ‘personal popularity rating’ at 47 percent, a number in the negatives for the first time since February. That’s the lowest pre-convention popularity rating for a current president since the 1980s. Down 7 percent from his recent high in April, the decline in favorability springs from women voters exclusively. In a small glimmer of hope for the GOP, Romney’s numbers showed a small increase post-convention, rising 5 percent in the past week.
