Elizabeth Warren: 'Michael Bloomberg should not be the Democratic nominee' Democratic presidential candidate Elizabeth Warren says billionaire Michael Bloomberg, who made his first appearance in a Democratic primary debate in Las Vegas, should not be the party's nominee to challenge President Donald Trump in the November election. "After his performance tonight, I have no doubt that Michael Bloomberg is reaching in his pocket right now and spending another $100 million to try to erase every American's memory about what happened on the debate stage," Warren says after the debate.
