No doubt about it, she has the best odds, with the exception of Oprah. I think the liberals would gladly vote for Oprah. Another possible is Michelle Obama, and yet, why anyone thinks she is qualified to be POTUS is a mystery to me. Being the First Lady is not a qualification. Being a lawyer with a suspended license is not a qualification either.
HRC has a real chance to beat Trump. She lives in 6-7 states, and the economy falters some, she has a shot. The rest do not. America is not going to vote for a communist, so Sander is not a real contender, and Warren is a lying sack of sh*t, who is also a bit of a nutjob. America would not vote for her either. And Biden is senile. His low functioning brain abilities are clearly on display every time he opens his mouth. He cannot complete a thought effectively.
