I do not doubt that there could be many Indians across the USA who would vote for Jindal based on complexion,
...however, there will also be many others who will not. If Jindal is to get the nomination, it should be because he is the best person for the job, and not because the Republicans think they can use him as a "token" to run a Republican Obama. if they try that, the people will see right through it and it WILL cost them votes, ...maybe not the ones that say "I don't care, I'm voting for him because he's Indian.", just like he said in the video - 'The important thing is the message, not the messenger." Those who focus primarily on the messenger always get it wrong... Palin is a good example. ha!
It will be interesting to see what transpires, ...especially as a result of events in recent days.
I don't doubt a President that looks like Jindal could go a long way towards undermining the prevalent theme of the past 8 years vis-a-vis those with his complexion. I doubt elements in Pakistan would be crazy about having an Indian in the white house tho, ...there are a lot of messages one could read into that, ...especially the paranoid in Pakistan.
