Charlie Cook: Republicans Will Lose Control of Congress

From the Cook Political Report of October 13th:

Category 5 Hurricane Heads for House GOP

Let's get the disclaimer out of the way: there are 25 days between now and the November 7 election and things could well change, making what follows obsolete.

That said, this is without question the worst political situation for the GOP since the Watergate disaster in 1974. I think a 30-seat gain today for Democrats is more likely to occur than a 15-seat gain, the minimum that would tip the majority. The chances of that number going higher are also strong, unless something occurs that fundamentally changes the dynamic of this election. This is what Republican strategists' nightmares look like.

Whether one looks at national or district-level polling data, or a survey like the new Democracy Corps survey that covered the 49 most vulnerable GOP districts, the conclusion remains the same: it is very ugly for Republicans.
