In an *unsurprising* rejection of congressional Republicans’ strategy, Americans overwhelmingly oppose undermining President Barack Obama’s health-care law by shutting down the federal government or resisting an increase in the nation’s debt limit, according to a poll released today. A majority of the public, 58 percent, is opposed to cutting off funding for the insurance program that begins enrollment today. By 72 percent to 22 percent, Americans oppose Congress “shutting down major activities of the federal government” as a way to stop the Affordable Care Act from going into effect, the national survey from Quinnipiac University found. By 64 percent to 27 percent, voters don’t want Congress to block an increase in the nation’s $16.7 trillion federal borrowing limit as a way to thwart implementation of the health-care law, which Obama signed into law in 2010 with a goal of insuring millions of Americans, known as “Obamacare.” A majority of the public, 58 percent, is opposed to cutting off funding for the insurance program that begins enrollment today. Thirty-four percent support defunding it.
