Obama Back on Top in 2 National Polls

John McCain’s post-convention bounce seems to be fading a bit, as Barack Obama reclaims the lead in several polls. A new CBS/New York Times poll shows the Democrat up 48%-43% as independents have swung back his way. Also benefiting Obama are concerns about Sarah Palin, whose favorable ratings have fallen off as voters worry about her readiness.

Another poll out today shows a similar result, reports Time’s Mark Halperin. The survey, conducted by Quinnipiac University, puts Obama up 49% to 45% over McCain. The Democrat also enjoys a 14-point lead among women, and his message on taxes seems to be working: 51% say McCain’s tax cut will benefit the rich and 9% the middle class. For Obama the numbers are reversed: 9% say his tax cut will help the rich, and 33% the middle class.
