Has President Obama betrayed the middle cl?

I know many people on the Left have defended how Obama came in to a huge mess to clean up after the Bush Disasters. I can agree with that, but I also believe he has taken actions that go against what benefits the Middle Cl. Between his continuation of the Wars in Iraq and Afghanistan, his new wars in Libya and Syria (am I forgetting one), the extension of the Bush Tax Cuts which the only thing they created was debt, a half-ed health care reform bill which benefits the sick for profit insurance companies, and now cuts potentially to Medicare and social security. When will the rich start paying their fair share? They should be paying half their income to taxes because they could afford it. If that bloated, pill popping drug addict Rush Limbaugh is so concerned about the debt, shouldn't he rally the troops to take care of it? My question, after venting all that is who do you suppose could potentially become a progressive Candidate in 2012, either as a Democrat or an Independent, who could challenge and potentially defeat President Obama?
