Vice Presidential nominee Paul Ryan’s headlining speech at the GOP convention in Tampa Wednesday night touched on many of the election’s defining issues. But it was also filled with prevarications — not just recitations of the conventions “you didn’t build that” theme, but on the very policy matters that have endeared him to the political establishment in Washington.

The speech effectively rallied his supporters in the audience. But on the merits it was chock full of misstatements of fact that undermine his reputation for brave, big ideas — which has hastened his rise through the ranks of the GOP.

Brian Beutler at Talking Points Memo focuses on Ryan's lies about Medicare, U.S. Credit Rating, the cloising of the Janesville GM Plant, the Bowles-Simpson Debt Commission and Protecting the Poor.

Jonathan Cohn at The New Republic also looks at the GM plant in Janesville, Medicare, the credit rating downgrade and protecting the weak, and in addition explores the Ryan's mendacity about the deficit.
