There’s a movement among Capitol Hill Republicans to defund Obamacare. With the president’s hugely expensive national health care scheme set to take effect Jan. 1, many of the law’s opponents view this fall’s battles over spending and the debt as the last chance to stop it, specifically by cutting off funds for its implementation.

But Republicans will not stop Obamacare. They won’t defund it. Their last chance to put an end to it was the 2012 election. They lost, and the chance is gone.
