The crucial job that voters in 2008 believed Obama could do best, and still want done in 2012, is to make the economy right, rein in the Wall Street greed merchants, save jobs and homes, and get the credit pipeline to businesses open. He also will continue to be the firewall against all efforts to gut Medicare, Social Security, and Medicaid. His ability to accomplish these things didn’t fully happen during his first four years. The modest proposals that he put forward to attack these towering problems only gave the GOP ammunition to rally millions to harangue, hector, and obstruct Obama’s efforts.
