( keep in mind that the Speaker of the House is 3rd in line and we've previously had Nancy Pelosi...regrdless of opinion if she took office that way it's not the same)
Kamala Harris will be President in the next election (just my prediction).
I think there is a fairly good chance we will have a female president within the next two decades. The democrats ran Clinton, and Fiorina ran in the republican primaries. It is only a matter of time.
