The ad is referring to Obama's fiscal year 2013 budget, which in fact calls for a tax increase on the upper-income taxpayers — not the middle class. Under the president's budget, the Bush-era tax cuts would expire at the end of this year for individuals earning in excess of $200,000 and couples earning more than $250,000 — but remain in place for all other taxpayers. So, the middle class would continue to receive the Bush tax cuts.
