Jindal is very popular with white conservatives. They will vote for him if he win the GOP primary. Winning the GOP primary will win the White House. Jindal have been hitting Obama a lot and conservatives loves that. However the favorite will be Rick Perry, Ted Cruz, and Rand Paul. If Jindal does not run or win the GOP primary he has a good chance of getting the VP slot or a post in the WH.
Louisiana is a very white conservatives state and he won the governorship twice. So the white support is there.
