Democrats are pulling out the big guns in tax talks. President Barack Obama and Vice President Joe Biden are meeting with Democratic congressional leaders today to discuss the “progress being made” in negotiations with Republicans. The meetings will give Obama a first-hand account of the lay-of-the-land on Capitol Hill, and perhaps a chance to discuss areas of potential compromise. Of course without Republicans in the room, it will be a one-sided discussion, but may provide some fresh ammo. OBAMA/
