Congressman Paul Ryan, the Republican budget guru, held a series of talks last week back home in Wisconsin. @triumph68 sends this pic from his talk in Oak Creek. Debt and deficit are not the same thing, but they're at least on a first-name basis. You can see, above, Congressman Ryan's chart about what he considers the root cause of debt. In short, it's the slate of entitlement programs Mr. Ryan wants to curb.
And below, you can see the view from the Center on Policy and Budget Priorities. In short, it's the Bush tax cuts, which Congressman Ryan supports in the name of lessening uncertainty. (Another view: the real problem is not uncertainty, either.)
