Politics have been part of the Patient Protection and Affordable Care Act since its passage in 2010. And politics, according to legal experts, stand in the way of fixing a glitch in the law that's at the center of several lawsuits challenging its legality. 

"With a normal, less-polarized law, so many of these issues that have popped up, Congress would go back and fix," said Iris Tilley, an employment and benefits attorney in Portland, Ore. "But because (the PPACA) is so politically polarized, Congress won't go back and fix anything. So, you have the executive branch fixing the law through regulation."

At the moment, at least four lawsuits are pending, all aimed at blocking the administration's attempt to fix the language surrounding the law's tax credits, or subsidies.
