Professional newsie Bill Dennis sums it up with this comment:
In my opinion, Democrats are enamored by the trappings of Democracy. They have trained themselves to believe that the more "input" and "diversity" that takes place, the better the end result. As a result, the process looks chaotic and by association, the result seems unpolished and flawed. Policies may in fact be flawed because they can be designed to accommodate and appease each member of the Democratic coalition (blacks, labor, etc) and put other considerations aside. Republicans come out of a corporate background, in which a board of directors pretty much rubber stamps the decision of the CEO (at least, in modern days it does), or at least keeps conflicts hidden in order to put on a united front. This makes the decision making process seem competent, when it may be no such thing.
