What We're Following This Morning

Republican presidential debate: As my colleagues noted, Marco Rubio and Ted Cruz thrived at last night’s presidential debate in Colorado. Jeb Bush? Not so much.

Vote for speaker: They nominated Paul D. Ryan yesterday, and House Republicans are poised to vote him in as speaker today. Ryan hopes to unite the fractious GOP caucus with greater ease that John Boehner, the man he’s about to succeed.

Game 2: The Kansas City Royals routed the New York Mets 7-1 to take a 2-0 lead in the World Series. Game 3 is tomorrow at Citi Field.
