Harris is better off being the running mate on the losing team, rather than top of the ticket.

Trump seems to be doing fine, in exactly the same situation.

Digression -

All the frothing at the mouth Dems here really need to understand how important it is to win the election. It's politics, not a test of ideological purity. And that the ONLY votes that count are swing voters in battleground states. If their candidate tees off the liberals in CA, MA, VT; that's perfectly fine (except maybe the rich donors and even they will donate anyway). Absolutely don't be Trump, but learn from him what's working.

This is war. Bloodless as long as the right makes it to be (to reverse-quote Kevin Roberts). Win first, worry about who is a better person etc later. No matter what, Trump is the Republican candidate and beating him is the only thing that matters. Not hand wringing about how American voters could possibly ever choose such a bad boy. They will unless you fight with every possible democratic weapon.

Without political power, all your great ideas are worth nothing.

Doesn't seem to be sinking in for some people here.
