Certainly the most striking outcome last night was Rhode Island. The exit polls in Rhode Island showed that the approval rating of the Republican incumbent, Lincoln Chafee, was 62 percent. 62 percent of the people who went to the polls approved of the job that Lincoln Chafee did, and they voted him out of office because he would have voted with the Republicans to organize the Senate. Tip O'Neill said all politics is local. Well, they weren't local last night. Politics last night were national.
Update 11/10 9:13 AM: The Economist's Democracy in America blog suggests that the Chafee result means that it means "voters know something about how their government works."
