What happened? One answer, I would submit, is that the president and his team found a better approach to governing: Instead of relying on the Democratic caucus in each chamber to deliver, they built up coalitions of their own that swayed public opinion in their direction and gave them leverage in Congress.  On the extension of tax breaks -- along with several other tax breaks the president wanted -- the White House cut a deal with Sen. Mitch McConnell and other Republicans. Liberal Democrats naturally cried foul, but the White House-GOP coalition sent a persuasive signal to the public that this was a reasonable compromise. Polls showed the public coming down in favor, and as night follows day, Congress voted the compromise into law. (Contrast how quickly the public turned against the health care reform when it was a Democrats-only bill.)  On "don't ask, don't tell," and on START, the White House had a different, but equally formidable, coalition that helped to turn the tide in the president's direction. The fact that Bob Gates -- one of the most respected defense chiefs in history -- and the chair of the Joint Chiefs, along with the poll of service members, came out in favor of repealing DADT made a huge difference in swaying both public opinion and Congress.  START appeared all but dead until the president assembled a group of Republican heavyweights -- from George H.W. Bush and Kissinger to Baker and Shultz -- whose vocal support for the treaty reversed the momentum.  In each case, there were also Senate stalwarts -- Joe Lieberman and Susan Collins on DADT, John Kerry on START -- who delivered, too.  From my biased perspective, I also thought the president was more effective because he seemingly played these fights more from the background than the foreground. We heard about him each day making phone calls, bringing in votes, but we didn't see him so constantly at the podium. It worked!
Voters who flocked to the Republican banner seven weeks ago are probably scratching their heads, wondering, "Who really won in November?" After handing the president and Congressional Democrats the
