I am pessimistic about this. It was 32 years from Al Smith, the first Catholic nominee, losing in 1928 to JFK winning in 1960 and 24 years from Jesse Jackson's first Dem primary run to Obama's win.
I think a woman who doesn't currently hold elected office will win the presidency sometime in the 2040's. She will be someone born in the 1990's or later.
My thoughts as well. I also think that United States will be more comfortable electing a woman if she's a Republican.
People used to say in the 90's/early 00's that the first African-American President had to be a Republican, and probably a hardline conservative or a military guy.
The talk was that it would be Colin Powell, who was military and a Republican, but not hardline conservative.
