PHILADELPHIA -- U.S. Sen. Elizabeth Warren of Massachusetts is the closer in tonight's line-up of the Democratic National Convention, and it's clear she'll attempt to enhance her role as Donald Trump's nemesis. Democratic officials have advanced a few of her lines.

The last one takes on the Rust Belt dynamic:

That's Donald Trump's America. An America of fear and hate. An America where we all break apart. Whites against Blacks and Latinos.      Christians against Muslims and Jews.  Straight against gay.  Everyone against immigrants.  Race, religion, heritage, gender – the more factions the better.,,, 

"But ask yourself this. When white workers in Ohio are pitted against black workers in North Carolina, or Latino workers in Florida – who really benefits?"
