[Lucius Cornelius Sulla]

'Also note that this poll surveyed registered voters, not likely voters — a sampling technique that would tend to favor Democrats and Obama a little more.'

That's a surprising admission from them. I'm not sure I agree that sampling "likely voters" would favor Democrats and Obama, though. Just ask President John Kerry.

I think you are misreading the original quote. I read it to have 'registered voters' as the subject and 'tend to favor Democrats and Obama' as the predicate. Imprecise grammar by the writer.

I think you’re right. That makes a lot more sense given the author’s other comment that the news was “uniformly bad” for Obama.
