That's a question best put to Bernie Sanders himself, but I think that he will probably put forward ideas that are related to the corrupting role of Citizens United and Buckley versus Valeo court decisions and the need to restore a by-and-for-the-people republic envisioned in our Constitution instead of the of-, by- and for-the-most-powerful system that we have right now.

Imagine if Congress always put the interests of polluters ahead of the health of our families. Our rivers and lakes would be choked with sewage. Acid rain would pour down from smog-filled skies. Hundreds of thousands more of our neighbors, friends, and loved ones would be victims of cancer, heart disease, and asthma.

There are two ways of looking at the talking filibuster. My way is as a form of unanimous consent.

We can no longer continue with a status quo energy policy. We must create sustainable clean energy jobs and leave the planet to our children and grandchildren in better shape than we found it.
