On Dec. 24, 2009, the Democratic-controlled Senate passed President Obama’s healthcare law with a filibuster-proof 60-vote majority, triggering a massive backlash that propelled Republicans to control of the House the following year. On the Senate side, going into this year's midterm elections, 25 senators who voted for Obamacare were already out or not going be part of the new Senate being sworn in next month. After Democratic losses on Nov. 4 and Saturday's defeat of Sen. Mary Landrieu, D-La., the number has risen to 30. In other words, half of the Senators who voted for Obamacare will not be part of the new Senate.
To be sure, it isn’t fair to attribute all of the turnover in the chamber to Obamacare. In some cases — such as John Kerry leaving his seat to become secretary of state, or Robert Byrd passing away — Obamacare clearly had nothing to do with the departures.
