After a meeting today at the White House, President Obama and Republican leaders promised to work together on major business before the end of the year. Treasury Secretary Tim Geithner will meet with members of Congress to resolve differences on the Bush tax cuts for wealthy Americans. Also high on the list are unemployment benefits and appropriations to keep the federal government running. Both sides agreed that the message from voters this month was that partisan gridlock is not acceptable. Is there a honeymoon? How long will it last?
