The Republicans have never run anyone other than white men, only one time a white woman VP. Going up against Obama the political timing is not ideal for yet again two rich old white men on the ticket. We would get a counter effect with either a Hispanic or a woman. Obama can’t win re-election without the Hispanic vote, and their loyalty to him is very breakable. The time is ripe for the current generation of Hispanics to escape the plantation. Women’s plantation-voting loyalty seems harder to break.
Thune isn’t old and Rubio is a Cuban/American.
It would be a winner.
