What Went Down At The Fourth Democratic Debate

I mentioned before how popular both Clinton and Sanders are with Iowa Democrats. But guess who’s even more popular? Barack Obama, who has a 91 percent favorable rating among likely Democratic caucus-goers. That’s why Clinton has pretty blatantly been trying to portray herself as Obama 2.0 tonight.

Sanders just said that political polarization is caused, in part, by our campaign finance system. Sanders is likely wrong. Most of the political science, including a recent book by Ray La Raja and Brian Schaffner, has found that states that try to limit campaign contributions have, in fact, encountered more extreme legislators.
