If you don't mind, as someone from Louisiana, I'd like to weigh in on Jindal, even though I missed the conversation last night.
First off, it's not race. His dropping poll numbers come from his constant campaigning out of state, continual slicing and dicing of the state budget to make a "balanced" document (as required by law) only to have mid-year deficits that cause yet another hit to higher ed and health care. Then he completely disappeared this session after his tax reform that appeared to be thrown together for conservative bonafides did not find a very receptive audience among the lawmakers who would have to deal with the changes long after he was gone.
There's also some of his big reforms passed in a way found unconstitutional, the investigation of how his former health secretary awarded a Medicaid contract, and his administration is VERY insular. It's either his way or the highway. He'll campaign on making government more transparent, but his office is locked down tight.
He was sold as a wunderkind, but now the emperor has no clothes. He's becoming Louisiana's version of Mitt Romney where everyone will be happy to be rid of him.
Personally, I don't think Jindal knows how to NOT be the golden boy. Everything he's done has been to ultimately run for president - Education reform, transparency, tax reform - but nobody wants him now.
But in the interim, looking to win the hearts of the state GOP is David Vitter, who's widely rumored to be running for governor. I'm not looking forward to that possibility. There's a good piece about this in the New Republic:

Anyway, hope that gives some background. I'll try to answer anything I missed.
