Paul Ryan's big speech Wednesday night was so filled with lies that there's disagreement on which were the five biggest. Definitely his lies about Medicare made the top five. Definitely his claim that President Obama failed to save a Janesville, Wisconsin, GM plant that had actually closed before Obama was inaugurated. But there's so much more to choose from.

On Medicare, Ryan repeated his claims that President Obama raided Medicare to pay for Obamacare, that "An obligation we have to our parents and grandparents is being sacrificed, all to pay for a new entitlement we didn’t even ask for." In reality, of course, Obama's cuts did not affect Medicare benefits, and Ryan's budget, the cornerstone of his reputation as a serious policy thinker, has the exact same cuts. And then some. Ryan would weaken Medicare for everyone, even the people whose benefits he says he wouldn't touch, and basically kill it off for people under 55 now.
