Yes it is. It is also easy for a underprivilaged person to make ugly accusations. Generalzations are fun!
I think Marco Rubio and Bobby Jindal would be able to energaize the right. Hispanic and Indian descent respectively.
Underpriviledged people experience the actions regularly, and their effects just about every day, that lead to the ugly accusations. Growing up, I and my friends experienced a little too much racism behind the smiles for me to believe it's gone. The feelings run deep and long. Maybe in another 50 years, skin color won't matter.
I'm sure Rubio and Jindal would excite some people on the right. I'm also sure they would scare off others on the right, to a greater degree than they would excite. I would be very pleased, as well as suprised, if either was a VP choice as early as 2024, or some other person who was not of European descent or not male.
