Outdated Attacks on Ryan

excerpt:
The Obama campaign points to old proposals by Rep. Paul Ryan in saying that Mitt Romney would pay “less than 1 percent in taxes” under Ryan’s plan and that seniors would pay $6,000 more for Medicare. Ryan’s 2010 budget proposal would have eliminated capital gains and dividend taxes — which were indeed the bulk of Romney’s tax burden for 2010 — but Ryan dropped that specific measure from subsequent budgets. The Medicare claim, too, pertains to a less generous plan Ryan released last year, not his most recent budget.
