Despite a mixed reaction to President Obama's convention speech and a mediocre jobs report this week, all three daily tracking polls show Obama expanding his lead in the presidential race over Mitt Romney.
It's important to note that much of the data in these trackers was compiled before the key speeches at the Democratic convention. To have gained ground so quickly, Nate Silver estimates Obama has been running ahead 7 to 9 points since Bill Clinton spoke.
Andrew Sullivan: "Yes, the ad blitz is coming; yes, the debates will be crucial, yes,
turnout matters a huge amount too, anything can happen, blah blah blah.
But right in front of our noses is some compelling data that in the
first real skirmish of the campaign proper, the Romney-Republicans blew
it."
