No, he is responsible for a tax hike by letting the Bush Tax Cuts expire.
They expired for ONLY those making over 250 thousand/year. Considering the percentage of wealth has increased significantly over the last thirty years for the super rich, so much so that we are Banana Republic levels. It was a great victory by Obama and this country.
It was the culmination of a 12 month battle that the Republicans fought tooth and nail over to keep the tax rates for the super rich at historically low levels. The Republicans held the tax rates for the bottom 98% hostage for the super rich until finally out manuevered by Obama.
There is nothing more clear about how the Republicans really feel about the middle class than payroll taxes. Republicans were AGAINST the payroll tax cut. Why? Because, the payroll tax cut helps the middle class, but is barely felt by the super rich. Hence the Republicans didnt care about it, and made it something the Democrats had to make concessions for.
