Mike Crapo has established himself as one of the Senate's most conservative fiscal hawks, consistently earning perfect scores from anti-tax organizations while championing limited government and deregulation. The longtime Idaho politician, who served in the House before moving to the Senate in 1999, has become a key Republican voice on banking and finance issues as the ranking member of the Banking Committee. A Mormon who built his early career as a tax attorney, Crapo has maintained an unwavering commitment to conservative principles throughout his decades in Washington, rarely breaking from Republican orthodoxy on major votes.
