Warren, by contrast, is exhorting her colleagues to “show some spine” and not “roll over” to drug companies and not “compromise with racism” by supporting Sen. Jeff Sessions’s (R-Ala.) nomination to serve as attorney general.

In doing so, she is taking a page out of Senate Majority Leader Mitch McConnell’s (R-Ky.) playbook. He marshaled Republicans in 2009 to oppose President Obama’s agenda right out of the gate, blunting the new president’s policy momentum and helping the GOP win big in the 2010 midterm elections…

“Elizabeth Warren does not represent the whole Democratic Party; she represents a very important wing of the party. But there are others of us who have a more pro-business [view], not a cave-in-to-Wall-Street thing,” said Rep. Gerald Connolly, a centrist Democrat from Virginia. “We don’t necessarily have that kind of ideological agenda.”
