Even if Nancy Pelosi conjures up parliamentary tricks to pass Obamacare, expect a long legal battle as states line up to sue the federal government over the unconstitutional federal takeover of the health-care system. Pennsylvania is one of 37 states that have threatened to sue over Obamacare.

From The Associated Press:

Idaho's governor on Wednesday became the first state chief executive to sign a measure requiring his attorney general to sue the federal government if the U.S. Congress passes health care reform that forces Americans to buy insurance.

"What the Idaho Health Freedom Act says is that the citizens of our state won't be subject to another federal mandate or turn over another part of their life to government control," Gov. C.L. "Butch" Otter said.

Constitutional law experts say Otter's action is mostly symbolic because federal laws supersede those of the states. But the movement reflects a growing national frustration with President President Barack Obama's health care overhaul.

Similar legislation is pending in 37 other states nationwide.

Democratic leaders in Washington D.C. are hoping to vote on the U.S. health care bill this weekend, but it is not clear if they have enough votes to pass it. The bill is Obama's top domestic priority and the health care issue could help determine whether Democrats retain control of Congress in the November election.

Last week, Virginia legislators passed a measure similar to Idaho's new law, but Otter was the first state chief executive to sign such a bill, according the American Legislative Exchange Council, which created model legislation for Idaho and other states. The Washington, D.C.,-based nonprofit group promotes limited government.

Otter, a Republican, already warned U.S. House Speaker Nancy Pelosi and U.S. Senate Majority Leader Harry Reid in December that Idaho was considering litigation if health reform went through.
