Barack Obama appears to have answered some key questions on voters' minds and enjoyed a significant bounce from the Democratic convention. He gained support from those who had supported Hillary Clinton in the primaries, and is allaying concerns that he's not ready to govern. Alaska Governor Sarah Palin, John McCain's running mate, is still unknown to many Americans, but enjoys favorable rating from a majority of those familiar with her in the first days after her selection.

Rasmussen's tracking poll, which had the race for the White House essentially tied on August 28th now shows Obama up by 6 points, joining Gallup's daily tracking poll, in which Obama's expanded his lead over McCain to 8 points. Hotline's latest shows a 9-point spread, and CBS shows Obama up by 8. Real Clear Politics rolling average of recent polls shows Obama up by 6.4 points.

In the Gallup Poll, Obama now has the support of 50 percent of registered voters (to McCain's 42 percent), the first time he's hit that mark and his highest level of support to date.

In CNN's polling, we get an indication of how the selection of Joe Biden and Sarah Palin played into the bounce. In its last pre-convention poll, which didn't mention vice presidential candidates, McCain led Obama by 2 points (42-40). In the latest, which did mention the candidates' running mates, Obama/Biden are up by 3 percent over McCain/ Palin (48-45), a 5-point swing. According to CBS, 71 percent of Americans said they watched the Dems' convention, including 63 percent of Republicans. CNN notes, "the convention made people who watched more likely to vote for the Democratic ticket." By a 51-32 spread, registered voters said the convention made them more likely to vote Dem come November.

Those are the headline numbers, but there are some interesting numbers within the latest round of polling. According to Gallup, the Democratic convention achieved a key goal: creating unity among Dems after a bruising primary fight.

Much attention was given to the fact that only 47% of former Clinton supporters said they were certain to vote for Obama in the pre-convention USA Today/Gallup poll, and that 16% of these voters said they were going to vote for McCain, with another 14% undecided.

The new polling shows that many of these disaffected Clinton voters have now returned to the loyal Democratic fold. The percentage of former Clinton voters who say they are certain to vote for Obama has now jumped to 65%. Although 12% of former Clinton voters persist in saying that they are going to vote for McCain, that's down from 16%, and the percentage who are undecided has dropped in half.

Overall, support for Obama among this group has moved from 70% pre-convention to 81% post-convention.
