Paul D. Ryan is officially in.
After receiving sufficient support from three major factions of the House GOP, the Wisconsin Republican announced Thursday he will run for speaker. "I never thought I’d be speaker," Ryan said in a letter to colleagues Thursday evening. "But I pledged to you that if I could be a unifying figure, then I would serve — I would go all in. After talking with so many of you, and hearing your words of encouragement, I believe we are ready to move forward as a one, united team. And I am ready and eager to be our speaker."
