Worse, Jindal has little new to offer. There could be up to seven other current and former governors running — many more than in 2012. Jindal also would have been the only serious candidate younger than 50 in 2012, but he’s joined by Ted Cruz, Marco Rubio and Walker in 2016.

And most importantly, Jindal’s ideological space is already occupied.

In 2012, Jindal would have mainly been competing for the affections of social conservative voters with Michele Bachmann, Perry and Rick Santorum. Only the latter two had ever won statewide office, and they both had their own problems. Now, Jindal has to go up against five other candidates for the social conservative vote, including four who have won statewide office before.
