The results speak for themselves. Simply put it was not a victory for President Obama or the congressional Republicans, but rather it it was a victory for the popular will. On every major issue the popular will was carried out. Public opinion favored a tax compromise, repeal of 'don't ask don't tell," passage of the Start Treaty, aid for the 9/11 responders and a rethinking of the FY 2011 spending plan. Public opinion was divided on the 'Dream Act" and that failed to pass.
Thus before rushing to conclusions that a new era of commity has descended over Washington, D.C., it more likely that on the controvesial issues that lie ahead there will be all-out street fights. The popular stuff will pass, but the really difficult fights over spending, taxation, environmental regulation and healthcare will be the norm.
