Could the US election be Nikki Haley versus Kamala Harris?

It's an extraordinary potential scenario but not necessarily out of the question. Donald Trump is forced to drop out of the Republican nomination race because of a conviction on a criminal charge, and Joe Biden decides to drop out for health and family reasons. Thus the November race would be an all-woman show - Nikki Haley steps in as the Republican nominee and Kamala Harris is slotted in for Biden's natural replacement. Whoever wins it would be America's first female president. This is the enticing scenario envisaged by Nikki Haley, the former South Carolina governor and way way back number two in the Republican race behind Trump. Ok, it's very much in her interests to suggest such a possibility but it's not totally unrealistic. Haley also said in an interview that if Trump did win the nomination, despite all his legal problems, he wouldn't win. Again, she just might be right. When voters actually go to the polls, a helluva lot of them might change their minds, unable to vote for a man who is facing 91 criminal charges. The bizarre thing is that in the South Carolina primary today, Trump will probably trounce Haley, even though she was the governor in the state. But she will be thinking longer term. Whatever the result in South Carolina, she will hang in there on the off chance her rival is forced out of the race. It makes a lot of sense. Even if Biden stays on for the election and refuses to drop out, Haley, ever the optimist, thinks she has a good chance of beating him if she gets the Republican nomination. But an election involving two women where a woman has to win? I quite like the sound of that.
