WASHINGTON _ U.S. Sens. Bernie Sanders and Elizabeth Warren traveled to Tuesday's Democratic debate in Detroit each seeking to emerge as the clear challenger to former Vice President Joe Biden in the presidential primary by dismantling arguments for a more moderate nominee.
The leading voices of the American left slammed proposals by some of their opponents for incremental change. Warren said "small ideas and spinelessness" could never win the White House back from Republicans, while Sanders said his critics were "afraid of big ideas."
But Biden's toughest competitors also spent much of the party's second presidential debate fending off criticisms that their ideas would strip healthcare choices away from Americans and, as Montana Gov. Steve Bullock said, "play into President Donald Trump's hands."
