In New Hampshire, a Public Policy Polling survey found Jindal had one of the best favorability ratings of all the possible candidates that respondents were asked about.

“He may be someone to keep a closer eye on moving forward,” PPP concludes.

But in South Carolina … Jindal is still not very well known, even among the tea party and evangelical sets that he’s attempted to woo on recent issues. The South Carolina poll was conducted by Winthrop University. Among those who are familiar with him, voter are closely split on whether they would or would not even consider voting for him.

Wisconsin Gov. Scott Walker leads the crowded field of potential candidates in both polls.
