"Sales is all about creating false expectations in people's minds." Another sterling Little Hawk epigram. The best salesmen I have met have been completely honest, but were skilled at determining whether there was a fit between the needs of the customer (or the Electorate, if you will) and their product (or their political agenda, if you will). They then make a case for a mutually beneficial agreement, and rely on the intelligence of the customer to make a reasonable decision.
Obama never advertised himself as a muck-raker or an enemy of captialism or a dictator or a socialist. He proclaimed himself to be a centrist who would try to move the country in a more rational direction, and take care of some needed issues. This is what he has attempted to do. Guest 999 had it pretty much right...he was left with a rundown, manure-filled stable and asked to produce Derby -winning thoroughbreds in 2 years or less.
So who is it that is being unreasonable?
