Senate Finance Committee Chairman Max Baucus (D-Mont.) announced April 23 that he will not run for re-election in 2014, raising questions on Capitol Hill about whether comprehensive tax reform can be done now that neither of the leaders of Congress's tax-writing committees will be in charge after the next election.

Baucus (D-Mont.), 71, announced his retirement after word leaked out through news outlets. In the House, Ways and Means Committee Chairman Rep. Dave Camp (R-Mich.) is required to give up the top seat due to term limits set by the House Republican leadership.
