There was cleavage on display Wednesday afternoon on C-SPAN2. It belonged to Sen. Hillary Clinton. She was talking on the Senate floor about the burdensome cost of higher education. She was wearing a rose-colored blazer over a black top. The neckline sat low on her chest and had a subtle V-shape. The cleavage registered after only a quick glance. No scrunch-faced scrutiny was necessary. There wasn't an unseemly amount of cleavage showing, but there it was. Undeniable.
