Did I say that? ;)
I think you might be referring to this comment: 'dick morris said the republican base represents the most educated subset of the american electorate.'
Actually tho, I do believe there is a difference in cognition. Ds and Rs are self-selected subgroups of Homo sapiens, so it's reasonable to hypothesize that there will be differences, including cognitive.
Because Republican/conservative philosophy appeals to reason, Rs tend to be analytic,; they are critical thinkers.
OTOH, Democrats rely on demagoguery, deception, emotion; the Democrat party, therefore, naturally attracts the emotive, the irrational and the incoherent.
Yes, you did.
And as and after I read the rest of your comments I couldn't help but think of Marshal Reuben J. Cogburn's reaction upon meeting Eula Goodnight in the movie Rooster Cogburn.
(If your not familiar with this classic, take what I said as a compliment.)
