Catholics outnumber other religious groups (not Protestants as a whole, but as divided up into denominations)  in Congress (this is not new – I believe Catholics have numerically dominated for a while)

Roman Catholics are the largest single U.S. religious denomination among members of the new U.S. Congress which also includes two Buddhists and a Muslim.

A survey published by Americans for Religious Liberty finds Baptists the second most common faith, followed by Methodists, Presbyterians and Jews.

The breakdown for the 535 members of the 110th Congress being sworn in Thursday:

Catholic 155; Baptist 67; Methodist 61; Presbyterian 44; Jewish 43; Episcopal 37; Protestant nondenominational 26; Christian nondenominational 18; Lutheran 17; Mormon 15; United Church of Christ 7.
