The annual progressive gathering known as Netroots Nation wraps up its annual conference in Detroit this weekend.
In the hallways and the meeting rooms, much of the buzz was about the presidential race in 2016 — and who might run on the Democratic side.
But Vice President Joe Biden, who gave the keynote address on opening day, didn't factor much into that speculation, despite being President Obama's wingman on everything from the stimulus package to the Affordable Care Act.
Biden was even ahead of the administration's position on same-sex marriage.
And now to our Friday political commentators - David Brooks of the New York Times. Hi there, David.
DAVID BROOKS: Hello.
CORNISH: And E.J. Dionne of the Washington Post and Brookings Institution. Welcome, E.J.
E.J. DIONNE: Greetings.
CORNISH: So as we heard President Obama - not directly calling out Vladimir Putin - but saying all evidence, so far, points to the Russian-backed separatists as being responsible for shooting down the Malaysia Airline jet.
We report next on a woman who's become a focus of presidential speculation. Hillary Clinton, of course, is an overwhelming front-runner for the Democratic nomination, but Elizabeth Warren has excited a lot of Democratic activists. The Massachusetts senator is spending her summer traveling the country.
