The Affordable Care Act, also called Obamacare, received no Republican votes in either the Senate or the House of Representatives when it was passed in 2009. In the Senate, the bill was passed with a total of 60 votes, or 58 Democratic Party votes and 2 Independent Party votes. The House passed the legislation with 219 Democratic votes.
The Affordable Care Act received 39 votes against it in the Senate, all from Republicans. One senator abstained from voting. In the House, the ACA received 212 votes against it, with 34 coming from the Democratic Party and 178 from the Republican Party. There were enough votes for the ACA in the Senate to prevent an attempt to filibuster the bill, while the House vote required a simple majority.
The ACA originated in the Senate, though both the House and Senate were working on versions of a health care bill at the same time. Democrats in the House of Representatives were initially unhappy with the ACA, as they had expected some ability to negotiate additional changes before its passage. Since Republicans in the Senate were threatening to filibuster any bill they did not fully support, and Democrats no longer had enough seats to override the filibuster, no changes could be made. Since any changes to the legislation by the House would require it to be re-evaluated in the Senate, the original version was passed in 2009 on condition that it would be amended by a subsequent bill.
