WASHINGTON/NEW YORK (Reuters) - U.S. Democratic presidential candidates took aim on Thursday at a rival whose name has not yet appeared on the ballot in the early voting states but whose television ads have blanketed the airwaves: billionaire former New York Mayor Michael Bloomberg.
Former Vice President Joe Biden and Senator Elizabeth Warren of Massachusetts, who lagged in the first two nominating contests in Iowa and New Hampshire, targeted Bloomberg over past policing tactics in the largest U.S. city and his comments about a mortgage practice widely seen as racially discriminatory.
