If she loses, will she run again? If so, will the Dem power brokers, particularly Obama, support her? If she runs again, and is nominated, would she choose Walz as her running mate?
If she loses, would Walz consider running for POTUS if Harris also runs? What if Harris doesn't run?
What is the likelihood that Harris is a sacrificial candidate? If she wins, that's icing on the cake because it wasn't really expected, and the power brokers have another puppet. If she loses, at the least the Dems didn't sacrifice someone with a good chance to win in 2028.
