Please don´t tell me the Dems are seriously contemplating nominating Kamala Harris *again*?!
I have no particular horse in this race (OK, maybe a cute little pony), but if anybody over there wants my advice, I would say that the "best" Dem ticket would be Newsom-Shapiro, while the "best" GOP ticket would be Haley-Rubio. Best from a European perspective, at least. In the long run, we´ll all be dead!
But surely nobody thinks Harris can defeat Vance? Although I suppose there is a slight chance, since Vance - after all - is no Trump. But that can be remedied by the neo-GOP very explicitly making Vance the constitutional place holder for Trump (or Trump jr).
