I don't like shifting the blame to all scientists, because some of them have been warning for over a hundred years (The Exceptional American Denial).

There is an establishment bureaucracy in scientific circles that is funding oriented.

So, money "talks science" too.

Then, even when some, like Hansen, reveal something the public needs to know it tends to be suppressed (In the Fog of The Presstitutes - 4).

While Dave Roberts, as usual, is spot on with respect to environmental issues, I believe his assessment of the politically possible was unfortunately locked into the realm of conventional wisdom.

His entire presentation was based upon the assumption that Hillary will be the Democratic Party nominee and that “the House is almost certain to remain in Republican hands.”

I got the impression that Dave simply fails to appreciate the dynamic and momentum of the Sanders political revolution, something I experienced first-hand by attending the July 29 meet-up that involved more than 100,000 Sanders supporters in 50 states.

When Bernie appears before record crowds, he is not simply adding potential voters. He is adding potential activists who will utilize a variety of means to evade the corporate stranglehold on the MSM so that, unlike past elections, this one could well be based upon where candidates stand on issues.

As I observed in Bernie Sanders Versus the 'Democracy Deficit', if this election were determined on the basis of where candidates stand on issues, as opposed to name recognition or personality, Sanders would win in a landslide. Although raw poll numbers reveal that Hillary Clinton still has a sizable but shrinking lead, they also reflect that a majority of Democrats simply don’t know about Bernie and his position on issues. As you noted during this segment of the BradCast, they also reflect that Bernie is the only presidential candidate in either party whose favorable numbers are greater than his unfavorable numbers.

The issue isn't just whether Sanders will ultimately overtake Hillary as the result of the debates and exponential spread of the Sanders political revolution. No president can, by themselves, deal with the significant issues (including the environment). But what Dave sees as politically impossible, Sanders sees as achievable so long as it has the backing of a vast majority of the American people.

I don't think Dave fully appreciates the dynamic that would accompany a Sanders nomination. During the 7/29 meet-up, Bernie noted that it is not enough for him to get elected. The rank-and-file of this people's revolution must target every office, federal, state and local. Where, at present, many Democratic candidates compromise themselves by seeking corporate funding, in the midst of this political revolution, that funding can become a liability.

As Bob Dylan so aptly put it
