Greg Sargent:

“…the proper response to a speech like this isn’t to carefully analyze the logic, or to find instances of hypocrisy; it’s to call the speaker out for telling flat-out lies to the American people. Paul Ryan has had what I’ve long thought was an undeserved good reputation among many in the press and in Washington. It shouldn’t survive tonight’s speech.”
