Correct me if I'm wrong, but is this the first time since 2008 that Obama's ratings have been in the negatives while the generic Democratic rating has been in the positives?
It always seemed that Democrats would ride on Obama's popular coat tails for everything, but that's no longer necessary. While in recent weeks Obama's oscillating numbers have plunged as far as a -5% spread, Democrats have only been going up. Often, sites like RealClearPolitics only update the generic congressional ballot rarely. The Democrats were at +2.3% for a while, and I was expecting to see this updated to a loss with Obama's plummeting numbers. Instead, it's been updated to + 4%. They are going in opposite directions.
Of course politics change fast, but it's pretty good news for Democrats and bad news for Republicans. If Democrats don't need Obama's popularity, it means the difference may be more innate to the parties themselves than analysts have been guessing.
