No he hasn't done a disastrous job. I doubt Votaire could make sense of Louisiana finances. Louisiana's problems come primarily from declining oil revenue and an unwillingness to raises taxes. This is as it should be. Revenues decrease, so should spending. I actually look at this as a plus for Jindal.
Rand Paul hasn't had executive experience, Jindal has. Legislators with no executive experience are unprepared for the responsibilities of the Chief Executive.
