Former Vice President Joe Biden is waging a two-front fight on health care reform by vowing in his latest presidential campaign proposal to protect the Affordable Care Act from Republicans and Democrats alike.

In announcing his plans to shore up Obamacare Monday, Biden equated Republican efforts to repeal the law with plans from other Democratic presidential contenders that would completely overhaul the U.S. health care system and eliminate private health insurance.

I knew the Republicans would do everything in their power to try and repeal Obamacare, Biden said in an email to supporters Monday. But Im surprised that so many Democrats are running on getting rid of it.

I know how hard it was to get passed, he added. Starting over just makes no sense to me.
