Is Honest Public Discourse a Fantasy? Ctd

Yes, I would say it is.  But I would add a couple of caveats:

First, this applies only to politicians, not to those who comment on politics or judge politicians.

Second, although there will always be incentives for politicians to be dishonest, these incentives can be minimized if constituents are themselves committed to knowing the truth and acting on the basis of solid facts and sensible arguments.
