Republicans sound foolish with this talk. Give Jindal a decade before we start calling him Reagan. We run the risk of sounding like the Obamamaniacs who jump on his bandwagon simply because he's articulate and not white. If Obama was a white politician, he wouldn't be considered seriously as a presidential candidate at this point in his resume.
"Could be Reagan" connotes a "down the road possibility". It is not the same as "calling him Reagan".
I think it's important to put him on people's radar screen so that they can begin to size him up early. Many people have never even heard of him. I suggest that you take the time to read the interview at my link in post #22.
