Never. Simple as that. We still have yet to have a Woman (Palin, Haley or Bachaman), Pentacostal(if Palin wins), Jewish (Cantor, Root), Latino (Rubio, or Bill Richardson))(including Italians and Spanish based groups), Asian (could happen if Mitch Daniels Nikki Haley, or Bobby Jindal wins) Morman (Mitt Romney)
Native Americans etc etc.
Lotta time left in humanity, Johanus.
Even as a Republican, I find it kinda funny that besides Richardson, JCL doesn't mention any Democrats.
Notice I also mentioned a third party candidate. Something my government teacher ,a liberal democrat, once told me that it would be advantageous to nominate a minority or a woman for president. I see a minority or woman presidential nominee between now and 2020 for the GOP.
