Getting Mr Trump out of the White House is important. Would I mind a woman in the White House ???? No.
Sadly Oprah, would carry the most of the woman's vote, and would get most of the electoral votes just as Hillary did. The hard core Trump Supporters, will not jump ship for a woman of color.
The Rock, would have a better chance of beating Trump, Wrestling is almost a religious experience in certain parts of this country , He is good looking and so far scandal free so he could get the womans vote, the gay vote and the black / Latin vote and certainly the redneck vote
