Hillary Clinton and Elizabeth Warren teamed up for their first joint appearance in Cincinnati yesterday, delivering repeated mutual pats on the back and fuelling speculation that the two could make history with the first all-female White House ticket.
Ms Warren, the Massachusetts senator who has become one of the Democratic party’s most prominent progressives, has reportedly made it to a shortlist of potential vice-presidents for Mrs Clinton and is being vetted for the job among with several others.
She has at times been considered a long-shot for vice-president, with some Democrats concerned that her populist views could alienate centrist voters and Mrs Clinton’s wealthiest backers, or that an all-female ticket could turn off some male voters.
