Tonight’s vice presidential debate in Danville, Ky. between Vice President Joe Biden and Rep. Paul Ryan will no doubt have several questions on the economy, which likely means Paul Ryan will have to answer questions from Biden and moderator Martha Raddatz about his budget plan.

If Biden needed a cheat sheet for Ryan’s budget plan, he might memorize this chart from the Center for Budget and Policy Priorities that shows that for fiscal year 2013, as House Budget Committee Chairman, Ryan’s budget proposal would get at least 62 percent of its non-defense budget cuts over 10 years from programs that serve low income Americans.

Ryan’s budget, which differs little from the one he submitted the year before, would make cuts to Medicaid and other health care benefits, food stamp programs, Social Security and other programs to a total of $5.3 trillion.
