President Barack Obama reveled Tuesday in the strong Obamacare enrollment numbers, touting them in remarks at the White House as evidence that his signature health care law is "here to stay." He said 7.1 million people have now signed up for insurance on the Obamacare exchanges, after a huge enrollment surge ahead of Monday's deadline. The number of sign-ups bested expectations, given October's glitch-laden rollout, and is expected to grow as more people finish enrolling. "This law is doing what it's supposed to do. It's working," Obama said. "As messy as it's been sometimes, as contentious as it's been sometimes, it is progress."
