It's narrated by Dan Mitchell. the video has two sections.
The first part reviews Congressman Ryan’s proposal and notes that it is based on a plan put together with Alice Rivlin, who served as Director of the Office of Management and Budget under Bill Clinton. Among serious budget people (as opposed to the hacks on Capitol Hill), this is an important sign of bipartisan support.
The video also notes that the “voucher” proposal is actually very similar to the plan that is used by Members of Congress and their staff. This is a selling point that proponents should emphasize since most Americans realize that lawmakers would never subject themselves to something that didn’t work.
