Klobuchar was the worst of the six.

"And then when it comes to Iraq, right now, I would leave our troops there, despite the mess that has been created by Donald Trump." -- Amy Klobuchar at Des Moines debate.

Of the six candidates on stage in Des Moines Tuesday night, Amy Klobuchar was by far, the worst.

She outflanked the others on the right on nearly every issue, from war to the economy, to the environment. She doesn't support a wealth tax or Medicare for all, tuition-free K-16 public ed, and if elected, won't repeal Trump’s tax break for the rich.

She wants to keep troops in Afghanistan and Iraq and keep nuclear weapons in southern Turkey. She defended the assassination of Gen. Soleimani. She's a big fan of Israeli policy towards the Palestinians and says that as president, she would "bring in American support again in a big way for Israel." She wants to keep the U.S. embassy in Jerusalem and leave in place the Trump administration’s policies on Israeli settlements.

And on it goes.

In other words, Klobuchar represents a wing of the Democratic Party that stands in direct opposition to progressives like Sanders and Warren on most of the fundamental issues.

She even slams Warren personally for being "too wonky."

So my question is, why would Elizabeth Warren decide to block with Klobuchar against Sanders Tuesday night? Was it just to score a few quick points against her long-time political ally in order to supplant him as the current progressive frontrunner? Was it simply an act of retaliation for Sanders' alleged "a woman can't win" comment in a private conversation? If so, it failed badly. It was a short-sighted, opportunist move that will divide the progressive wing of the party and will likely hurt mainly her as well as Sanders' chances of winning the nomination.

I hope not.
