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