Clearly, the word is out to keep this guy off the news.

Isn't it a little early to conclude that a mere day and a half after his interview? Unless he was on tv every single day beforehand, there's no indication he's getting less attention than he was before.

listening to Rubin's presentation, was his view that only Canada had the resources to pick up the slack.

Perhaps you should listen again, then - he also mentioned Angola, Venezuela, and Brazil as future sources of oil to replace Mexican production (3:17 into the interview).

Moreover, he flat out states that replacing conventional oil with non-conventional oil is not a problem (2:30 into the interview), other than keeping oil prices high, so it's not at all clear that his views agree with those of people here.
