For a poll taken right after the Democratic convention, it really only has Obama doing two points better than the last PPP poll, taken about a month ago. Sure it's better news for Obama than Romney, but this is probably one of Romney's better polls in the last couple days.
Uh no, at this point any expansion one way or the other is pivotal, given how small the slice of the undecided electorate is becoming. Plus, if Romney's support has not grown, then it means that the RNC didn't really sway anybody.
Obama also hit 50% in this poll, which is a pretty big deal.
