Michael Hudson: Back in the 1950s, I used to go to socialist meetings, and people would say, why do the trade union people keep thinking they’re locked into the Democrats? And the answer is: well, that’s the two-party system. There isn’t really room for a third party here. And all the Republicans have to do is say, no, we’re worse, and it just scares people to actually vote for the Democrats. But people have been asking that question for 60 years, and nobody’s come up with a better answer since.
