Lawmakers in the House voted 220 to 215 on Saturday night to approve a sweeping overhaul of the nation's health care system. Only one Republican voted for the bill, and 39 Democrats opposed it, including 24 members of the fiscally conservative Blue Dog Coalition. An overwhelming majority of the Democratic lawmakers who opposed the bill — 31 of the 39 — represent districts that were won by Senator John McCain, Republican of Arizona, in the 2008 presidential election, and a third of them were freshmen. Nearly all of the fourteen freshmen Democrats who voted “no” represent districts that were previously Republican and are considered vulnerable in 2010. Geographically, 22 lawmakers from southern states formed the largest opposition bloc. Below are details on the Democrats that opposed the health care legislation in the House.
