JIM DEMINT was elected senator of South Carolina in 2004 and then chairman of the Senate Steering Committee in 2006. For standing up against wasteful spending in Congress and saving Americans about $17 billion, Wall Street Journal editor Steve Moore called DeMint the "taxpayers' greatest ally." DeMint was also recently ranked as the Senate's most conservative member by National Journal and as the No. 1 senator voting for responsible tax and spending policies by the National Taxpayers Union. The senator and his wife, Debbie, have four grown children, are doting new grandparents, and live in Greenville, South Carolina.
