The National Labor Relations Board on Friday officially dropped a case challenging Boeing's efforts to start a non-union manufacturing plant in South Carolina.

Here are some of the reactions coming from The GOP 2012 presidential field.

Newt Gingrich: "The NLRB's suit was a politically motivated assault on the rule of law by President Obama and his big labor allies. The founding fathers warned that when government grows too big the law would be usurped for political purposes. This case was an example of that.This is a victory for South Carolina and all right-to-work states, and a reminder that the American people will not be dictated to by out-of-control bureaucrats in Washington."

Mitt Romney: "The National Labor Relations Board's decision to drop its suit against Boeing is a welcome step. But the fact that the Board acted at the request of the union bosses tells us all we need to know about who is calling the shots. While it is good news for the people of South Carolina, it does little for workers and businesses around the country who depend on a fair and impartial U.S. government. Thanks to President Obama's appointees, the NLRB has become a rogue agency that tramples on the rights of American workers and businesses, injecting job-killing uncertainty into the economic climate."

Rick Perry: "The Obama Administration's dangerous and inappropriate action against Boeing and the right to work state of South Carolina remains a frightening reminder of Washington excess even with the NLRB dropping the case. Unaccountable federal political appointees should never have the authority to tell a private company where it may or must build factories.  

"The NLRB action was a political payoff for the Obama Administration's liberal big labor organizers, and remains a strong example of why President Obama must be defeated and Washington must be seriously overhauled."
