House Republicans are supposedly in chaos. Yet somehow the earth keeps spinning on its axis, and yesterday the House actually passed legislation to allow sale of American oil overseas. What’s really in chaos is Obama’s foreign policy. And maybe the Democratic Party’s presidential field. Let’s see what the debate on Tuesday brings. A strong performance by Bernie Sanders might throw Hillary into a fatal tailspin. And/or she’ll get nasty with Bernie in unattractive ways. Meanwhile the rest of the country will be saying, “Who’s this Jim Webb guy? Why is he here?”
