Hillary Clinton has been polarizing her entire political career. But now, ahead of a second presidential run, she wants to be a uniter, not a divider. People should “get out of the kind of very unproductive discussion that we’ve had for too long, where people are just in their ideological bunkers, having arguments instead of trying to reach across those divides and have some solutions,” she said, speaking to labor leaders and policy wonks during a Monday event at the Center for American Progress, a liberal think tank that doubles as the Clinton administration-in-waiting.
