The Globe and Mail reports in its Tuesday edition that Democratic presidential hopeful Kamala Harris presents herself as a continuity candidate, one who will build upon Joe Biden's legacy and distill his grand vision into practical, relatable measures that touch ordinary voters. Guest columnist John Rapley writes that Ms. Harris has riled her critics with her plan to lower inflation by going after price-gougers. Ms. Harris proposed using what amount to antitrust measures to target oligopolistic behaviour in price-setting, a long-established American practice that Mr. Biden revived. As a signal of a Harris administration's general orientation, on the side of ordinary people, it sends a message to voters. In that respect, a key test of her beliefs will come with her decision on whether to keep Mr. Biden's key trust-busters, Lina Khan and Gary Gensler. Some of her big donors have expressed their deep distaste for the two regulators -- Ms. Khan, chair of the Federal Trade Commission, and Mr. Gensler, chair of the Securities and Exchange Commission. If she ignores the donors' call to sack them, that will suggest she will continue Mr. Biden's program of reining in the plutocrats who have become so powerful in American life.
