The biggest casualty of a Bloomberg run could be @PeteButtigieg who is currently the fav among moderates who think Biden is fading and Warren/Sanders are terrifying.
He could also be the beneficiary. With greater attention on Bloomberg's interest in a more moderate, pragmatic candidate, @PeteButtigieg could get more looks. Right now, he's competing with Warren for college ed vote, and Biden to a lesser extent at moment for the moderate vote.
