There's been much concern about Obama 'moving' to the center now that the primary battle is over. It is inside the beltway common 'wisdom' that Democrats must never be too liberal and must always seek bipartisanship to win. Bullshit. Digby and dday have covered how well that works. The so-called center has been shoved so far right by the GOP, it's firmly in wingnut territory.
Two analogies here. #1. The U.S. is the Titanic. John McCain will steer to the right, away from the iceberg - but deeper into the icepack. If Obama moves to the center, we stay right on course for the berg. Only a hard left might get us to safety.
#2. If you're flying to a destination with a wind pushing you to the right, you'll never get where you're going if you keep the plane pointed straight ahead. You have to angle the plane to the left to compensate for the crosswind (it's called a crab angle) if you want to stay on the desired course. The more wind, the greater the crab angle needed.
Compare, contrast, discuss.
