New York senator Kirsten Gillibrand has had a banner few months.

She racked up the best record on Donald Trump’s cabinet nominees, opposed Neil Gorsuch’s Supreme Court nomination, railed against Trump’s immigration executive order, and grilled his appointees in widely shared videos. She was even singled out by the Trump team — along with Vermont senator Bernie Sanders and, of all people, New Jersey senator Cory Booker — as one of the “radical liberals” blocking his anti-Muslim travel ban.

Now her name is being floated as a progressive presidential candidate in 2020.
