Kamala Harris/Pete Buttigeig 51% roughly 289 EV
Mike Pence/Marco Rubio 48% roughly 249 EV
Before everyone freaks out about Kamala winning Indiana, remember, Pence was really unpopular there before he became VP. He might have actually lost his reelection campaign if Trump hadn't put him on the ticket.
Yes, Pence was extremely unpopular and probably would have lost to Gregg, but that’s because Gregg is a great candidate for Indiana. Kamala can’t cut down the margins enough in rural Indiana to pull out a victory.
