The lame-duck session of Congress is hard to keep track of. Today's sure thing is old news by tomorrow, and nobody knows how long it's going to go on. The tax bill and the omnibus spending package were dealt with last night, but what about "Don't Ask, Don't Tell," the DREAM Act and the START Treaty? Is Barack Obama "triangulating" with Democrats and Republicans, just like Bill Clinton? Is he abandoning principles or finally getting real? What are the prospects for next year when Republicans will take over the House? Will it be time to get down to business or the start of the next campaign?
