“He’s done the best he could under the circumstances,” Carter said of Obama. “His major accomplishment was Obamacare, and the implementation of it now is questionable at best.”
“He’s done he best he could.” Which, clearly, is not even good enough for government work.
You can just imagine Carter wanting to reach out and pat Barry on the head: Nice president, now go play some golf.
