Agreed, Robert, and this is Jay Hanson's assertion as to why democracy is fundamentally incapable of grappling with peak oil. I don't necessarily agree with all of Hanson's conclusions, but I do on the topic of democracy. People don't vote for whomever tells them the truth. People vote for whomever makes them feel good in whatever personal value space they currently hold.
As a practical matter, vote for the amiable drunk. Do not vote for the dry drunk, the drunk in denial, or the angry drunk. (Bush). Amiable drunks make the best politicians.

Mosca and Pareto shot the notion of representative democracy to hell definitively over 100 years ago. And they missed a few points.
