In September 2009, Lincoln pledged to filibuster any legislation containing a Public health insurance option, such as the Affordable Health Care for America Act (the Democratic-controlled, House of Representatives' preferred health care reform bill). This move came as a surprise to liberal Democrats, who largely interpreted the move as a betrayal of traditional Democratic values. Lincoln voted in favor of the Patient Protection and Affordable Care Act, the Senate bill that eventually became the Barack Obama administration's health care reform law. However, she voted against the Health Care and Education Reconciliation Act of 2010, a package of amendments to the Affordable Care Act—passed via reconciliation process, to circumvent united Republican attempts to block the bill's passage—in the Senate.
