Some conservative Republicans in the House want to roll back much of the new Medicare drug benefit and the "No Child Left Behind" education law that President Bush made domestic hallmarks of his first term, a GOP lawmaker said Wednesday.

While praising Bush's leadership on fighting terrorism and passing tax cuts, Rep. Mike Pence of Indiana said it was important for Republicans to reassert conservative values that led them to control of Congress.

"The fate of the Republican majority ... will be largely determined by whether or not we rediscover those principles of limited government that more than anything else propelled us to majority status," said Pence, chairman of the Republican Study Committee, a group of more than 100 conservative House members.
