If there was any doubt that a woman could lead this country, it was put to rest last night. From the moment she crossed the stage and reached out her hand to greet Donald Trump, Kamala Harris dominated the presidential debate on substance, style and seriousness.

Like the prosecutor she used to be, the vice president made her case sharply and cleanly, identifying and exploiting Trump’s weaknesses. In doing so, she effectively undercut her opponent’s longtime strategy of snidely attacking, denigrating and even looming over women in debates.
