States' rights is rallying cry for lawmakers

Whether it's correctly called a movement, a backlash or political theater, state declarations of their rights–or in some cases denunciations of federal authority, amounting to the same thing–are on a roll. Gov. Mike Rounds of South Dakota, a Republican, signed a bill into law on Friday declaring that the federal regulation of firearms is invalid if a weapon is made and used in South Dakota. On Thursday, Wyoming's governor, Dave Freudenthal, a Democrat, signed a similar bill for that state. The same day, Oklahoma's House of Representatives approved a resolution that Oklahomans should be able to vote on a state constitutional amendment allowing them to opt out of the federal health care overhaul.
