Newly combative Democratic presidential candidate Elizabeth Warren

On Wednesday night, Elizabeth Warren earned rave reviews for her assertive, combative performance at the Democratic Party presidential debate in Las Vegas, Nevada. Warren spent most of her time going after Mike Bloomberg, and by many accounts, Warren eviscerated Bloomberg. But the question becomes, to what end? Warren was considered to be in the “left lane” of the nomination contest, and that lane is dominated by Bernie Sanders, yet Warren barely attacked Sanders. Likewise, Warren (and to be fair, her competitors onstage) barely laid a glove on Donald Trump, who, after all, is supposed to be the subject of their competition. So, what is Elizabeth Warren doing, and did it help her candidacy?
