The Cook Political Report is a well-respected, independent take on the status of political races. Tonight, Cook posted his latest ratings for the House of Representatives, and the movement he reports is stunning, foreshadowing a potentially major shift toward the Democrats.
He rates only one presently Democratic seat as highly vulnerable (he calls it a "tossup"), only ten presently Democratic seats (including the one tossup) as even competitive. Meanwhile, he sees eleven presently Republican seats as tossups, fully thirty six Republican seats as genuinely competitive, and another nineteen as potentially competitive. Six Republican seats in the New York delegation are rated as in play.

Observation: If Democrats can hold their own seats, and take half of the Republican seats that Cook sees as competitive, the Democrats take control of the House.

But not one vote has yet been cast. So what does this all mean? Find a race, get involved and make a difference. It's doable.
