To me, the worst kind are those who are ignorant AND stupid. An ignorant man does not know the issues at hand. A stupid man knows what the issues are, but does not study and evaluate the facts before drawing conclusions. Thus, on issues for which Obama is not ignorant he's stupid.
And what about the RINOs and globalist ptb who would rather run one of their own and lose than cede power to true constitutional conservatives, who can and will articulate the issues at hand? The RINOs and globalist profit whores are neither ignorant nor stupid....they're self-centered, elitist, and profiting from the destruction of the US.
What a choice.
Machiavelli described three types of men. The first and best were men who would evaluate a problem, properly analyze it and devise a rational solution. The second would be a man who when confronted with the same problem does not fully understand or is able to devise a solution on their own, but when instructed grasps the solution and becomes effectual. The third and worse kind is the man who neither understands, solves or is capable of receiving instruction. Obama is in the third category. Also such people are often narcissistic and arrogant.
