A few excerts from the Times story:
Handsome, youthful, Cuban American and Republican, U.S. Sen. Marco Rubio of Florida has been mentioned repeatedly as a potential running mate for Mitt Romney — in part because of hopes that the presence of the first Latino on a major national ticket would draw that key voting group Romney's way.
But outside of his enormously important home state, the prospect for that sort of boost seems less than likely.
One complication is internal rivalries amid the diverse group of 22 million potential voters that, for demographic purposes, is treated as one unified electoral bloc.
"Mexicans and Central Americans historically have a reason for being Democrats, and Cubans have good reasons for being Republicans," said Jesus Hernandez Cuellar, a Cuban American editor of an online magazine. "I don't think the great electoral mass, the Mexican Americans, will change their point of view on the election just because of Marco Rubio."
