(AP) -- White House hopeful Ron Paul says he likes the idea of states deciding which federal laws they shouldn't have to follow because they deem them unconstitutional.
The libertarian-leaning congressman from Texas says nullification could be a helpful check on the federal government and that it would be a lot smaller if that principle were part of the Constitution.
Paul is in South Carolina making his final pitch to voters ahead of Saturday's first-in-the-South primary there. He spoke Tuesday at the South Carolina Statehouse, surrounded by icons of the Civil War.
