Overall thoughts about the race: Harris might be dying off prematurely. On one hand, I would really like her to put up a strong fight and therefore take from Elizabeth and Biden. OTOH if she flops completely and drops out, this makes more room for Buttigieg. Imagine a four-person debate with three career politician septuagenarians and a 38-year-old articulate, handsome war veteran.
Of course, the candidate I'm most concerned about is Elizabeth.
Personally, I think if Harris drops out it'll be more of a gain for Warren or possibly Booker. As much as I don't agree with the nature of this, you can't underestimate the female&minority aspects that are a draw here before policy differences come into play.
What do you mean about being concerned about Warren though? Or do you just mean in relation to your bets
