Over at Media Nation, Dan Kennedy asks of Colin Powell's endorsement of Barack Obama: "Is this as big as everyone thinks it is?"

We shall see. But here's my prediction: thanks to the memory of Powell's fatally flawed, pre-Iraq War speech to the U.N, his endorsement won't be quite as valuable as it otherwise would. After all (conservatives can argue), Powell was wrong on Iraq--so what if he's wrong on Obama, too?
