(The US Congress, a legislative body, is made up of two houses: The Senate (100 members) and the House of Representatives (435 members). Ed.)
The 112th Congress, like the U.S. public, is majority Protestant and about a quarter Catholic. Baptists and Methodists are the largest Protestant denominations in the new Congress, just as they are in the country as a whole.
A few of the country’s smaller religious groups, including Episcopalians, Presbyterians and Jews, have greater numerical representation in Congress than in the general population. Some others, including Buddhists and Muslims, are represented in Congress in roughly equal proportion to their numbers in the adult U.S. population. And some small religious groups, such as Hindus and Jehovah’s Witnesses, are not represented at all in Congress.
