Is Wisconsin battle inspiring Right-to-Work nationally?

Should workers be forced to pay union dues even if they don't want to belong to a union? Republican US Senators are trying to make the same move nationally that is occurring in Wisconsin.

A group of conservative U.S. senators has introduced a bill to restrict unions from forcing workers to join and pay dues as a condition of employment.
The move on Capitol Hill comes as several states consider what's known as "right-to-work" legislation -- proposals that have met stiff resistance. Indiana Republicans recently shelved their right-to-work bill after it sparked protests at the capital and after Democrats fled the state to block it, mimicking the tactic used by Wisconsin lawmakers holding up Gov. Scott Walker's anti-union proposal.
But GOP senators in Washington said national legislation is needed to stop the "strong-arm political tactics" they claim labor bosses are using to compel new employees into joining their ranks. They introduced the National Right to Work Act Tuesday. . . .
