Obamacare success?

These numbers show success according to Krugman.  However, let us not3 that Texas which refused both the exchange and the Medicaid expansion has outperformed all the public sector states by doulble.  So Texas seems to be doing this right.


For example4, Krugman's own state, New York, has grown by a mere 1.5% since the crash, but Texas has grown by 4.2%.  Is it weather or better government? California which has both the exchange and medicaid expansion only grew2 by 2.1% over the whole period.
