Bloomberg’s careful avoidance of anything resembling an unscripted moment doesn’t necessarily mean he’ll be a debate pushover. In 2009, The New York Times reported that in his last mayoral debate, Bloomberg showed “the ferocity of a bulldog” and “turned almost every question put to him into an attack on his rival” (via Tom Watson). This time around, Bloomberg will have to decide whether it’s worth changing his focus from Donald Trump to his Democratic opponents; if he does, he’ll have to message against more than one person. Bloomberg will also be facing somewhat sharper debaters than he did in 2009.
Former Vice President Joe Biden, Sens. Amy Klobuchar, Elizabeth Warren, and Bernie Sanders, and former South Bend Mayor Pete Buttigieg had previously qualified for the debate.
