He probably has the same goal in mind...the destruction of the US economic engine, and Warren and Sanders would both get that done.
Dont kid yourself. Warren and Sanders, NOT THE SAME THING. Barack and his pimp ValJar will do anything to prevent Bernie from winning. Bernie cant be bought or blackmailed. Other than threatening the health of his loved ones, sanders is not for sale and hes not corrupt. The Obama team wants to rule behind the scenes and they cant with the Bern. Warrens their desired puppet.
