Me of all people? Did you think I was ethnic-ish or something? White dude here.
But what you're saying only holds true amongst the kind of people who would never vote for a Republican/conservative, anyway. (And I'm not even sure that dynamic is present among those of Jindal's ethnicity.) A conservative of color would blunt some of the race-baiting that will inevitably be used in 2012. After all, how dare those Republicans take away the first black president's second term? Racists!
Puh-lenty of ethnic Indians form the sub-continent live hereabouts. They are the sort of folks who would go to school board meetings and pound the table with the rest of their engineer/technically-minded co-workers.
Matter of fact, the last school board election, I voted for a technically-minded Indian guy who was doing just that. Also, proposing very radically increasing the standards and resources devoted to the sharper kids in the school district drawer and boost the math & science curriculum, which has languished as more anchor babies enter the district. The local anti-religious types used his fundy Christian beliefs as a club to beat him, but they, despite their pathetic claim to Reason, would never have voted for an unapologetic Christian of any stripe.
