In this March 23, 2010, file photo, President Barack Obama reaches for a pen to sign the health care bill in the East Room of the White House in Washington. Obama’s re-election has guaranteed the survival of his health care law. Now the administration is in a sprint to the finish line to put it into place.

Republican governors will have to decide whether they can join the team and help carry out what they’ve dismissed as “Obamacare.” And the administration could stumble under the sheer strain of implementing the complex legislation, or get tripped up in budget talks with Congress.
