How five newcomers could change Senate: "Call them the five horsemen of the Republican Revolution: incoming US Sens. Richard Burr of North Carolina, Tom Coburn of Oklahoma, Jim DeMint of South Carolina, John Thune of South Dakota, and David Vitter of Louisiana.
"Their arrival in the US Senate next week gives a powerful boost to both fiscal and social conservatives on issues ranging from judicial nominations and abortion rights to tax reform. It also tips the number of former House members in the Senate to 52 percentthe first time it has passed a majority. More than just an additional five GOP votes, they bring a hard-driving style and ideological focus that is at odds with the collegial culture of the Senate."
