Over twenty states filed a lawsuit last week targeted squarely at the heart of Obamacare. The battle is being led by the Attorney General of Texas, Ken Paxton. He argues that because Congress—in the tax reform bill passed into law late last year—effectively ended Obamacare’s requirement that people buy health insurance, the rest of the law cannot stand.

The lawsuit poses no immediate threat to Obamacare.  But if it makes its way to the Supreme Court—as four other cases on the law already have—the law could be in jeopardy, especially if one of the liberal justices on the Court steps aside soon and President Trump gets the opportunity to name a replacement.

This all reminds us of just how unpopular Obamacare continues to be. 

If and until the courts step in, it’s still up to Congress and the Trump Administration to deal a decisive blow to Obamacare.
