Other findings
* A majority of voters (55%) give Obama a grade of A or B for convincing them to vote for him. That is a higher grade than for any Democratic or Republican candidate in the past three campaigns. By contrast, just 32% give McCain a grade of A or B.
* A small but stable minority of voters (12%) of voters believe that Obama is a Muslim. That is about the same percentage that said Obama was a Muslim in March (10%).
* Most Democratic and Democratic-leaning women voters (60%) want Obama to choose Hillary Clinton as his running mate. But voters who supported Obama in the Democratic primaries remain cool to this idea.
* A quarter of liberal Democrats say they have contributed money to a presidential candidate in the past year, about double the proportion of conservative Republicans who have donated (13%).
* Democrats who favored Clinton for the nomination remain critical of Obama. Just 35% say he is more personally qualified than McCain to be president; former Clinton supporters are split as to whether McCain or Obama could better deal with terrorist threats.
* Conservative Republican voters are decidedly less optimistic about their party’s chances in the fall than they were just a few months ago. Just 49% say McCain is mostly likely to win, down from 71% in April.
Bottom line: Obama hasn’t reached his ceiling yet, but it’s not so clear that’s true for McCain.............
