I believe that my duty is to follow my conscience and vote what I think is in the best interest of the country, and the political risks will have to abide.Sen. Arlen Specter • On his decision to switch parties and support the Affordable Care Act, a switch he made in 2009 amidst controversy. The change cost him another term in the Senate — he lost a challenge to Rep. Joe Sestak in 2010, and Sestak lost to Pat Toomey in the general election. Specter managed to become the longest-serving senator in Pennsylvania history despite suffering numerous health problems — including two benign brain tumors in the 1990s, and two separate bouts of Hodgkin’s disease in the 2000s. Specter died of complications from non-Hodgkins lymphoma on Sunday.
