It's the mating call of the Naderites: there's no difference between the Democrats and Republicans. They're both corporate parties; the only difference lies in how far right-of-center they lie.

But there is a difference. It's not as stark as most progressives might like, but it's there, and it makes itself felt over time. That's why, as frustrated and as impatient as we might be, we've got to pay attention. With Joe away, Abe looks at the quadrennial liberal presidential dilemma.
