White blue-collar and working-class voters have left the Democrat Party in droves. In 2016, there will be a big drive to woo them back. That is why Obama is resurrecting income inequality, minimum-wage, and other class-warfare issues to set the plate for 2016.
Now we all know that Warren is a phony populist (as well as a phony Indian), she herself is an elitist snob and she has about as much in common with the working man as Obama does. But she is an excellent stump speaker, and low-information working voters will flock to her. They'll especially vote for her if Jeb Bush is the GOP nominee.
So dismiss Warren at your own peril, but if she's nominated she'll be tough to beat.
He’s already going after that issue, and they’re furious about it:
