C-SPAN showed his speech yesterday at a fundraiser for Sestak held in Philadelphia. Of course the crowd was partisan and Obama was in his usual stridently partisan mode. He said the Republicans want to spend $700 billion, referring to maintaining the tax cuts for those making over $200,000 a year (in other words, when the government doesn't take money from people it's the same as spending money). He also lashed out again at the Supreme Court ruling allowing "special interests" to spend money in campaigns.
I only watched a little bit of it--there were probably other attacks since that's what his speeches are mostly composed of.
Obama, the moronic POTUS, does not believe that there is an optimum tax rate that maximizes revenue to the treasury - he thinks that 100% tax rate for the “wealthy” would be great, “social justice” you know.
