President Barack Obama has one of the biggest leads we've seen for him in quite a long time in a new Pew Research Poll: He's up 10 points over Mitt Romney.
Don't take much from it, though. Pew's sample of registered voters is highly skewed, oversampling Democrats by almost 20 points. Pew surveyed 1,956 registered voters. Of those, 42 percent were Democrats and just 23 percent were Republicans. We can't remember a poll being that imbalanced.
Pew's poll in June also slightly oversampled Democrats and gave Obama a 7-point lead.
So what we can take from this is that Independents are still split on the two candidates, but they've trended toward Romney in the past few weeks. Independents in the poll voted for Romney, 45 percent to 43 percent. That's a 3-point swing from Pew's last poll, when Obama was up 46-45.
