Used this definition:
A benevolent dictatorship is a form of government in which an authoritarian leader exercises absolute political power over the state through elected representatives. A benevolent dictator may allow for some democratic decision-making to exist, such as through public referendums.
Characteristics:
Many dictators’ regimes portray themselves as benevolent, often tending to regard democratic regimes as messy, inefficient and corrupt, but few are widely viewed as such outside their country or supporters.
Obama sees himself as a benevolent dictator. Views the constitution as flawed. Sees working with congress messy and inefficient, perhaps necessary or useful when controlled by his party, but will workaround either (constitution or congress) to get his way.
I accept your definition and application. I think part of being a dictator is exterminating real political opposition. It’s what 0bama is doing to “fundamentally transform” America. There is nothing benevolent about that, in the ordinary usage of the word.
