You could say that Obama is a bad president, but the truth is that he isn't even a president at all. He's an empty suit. Even a bad leader actually LEADS. He, as another commenter noted elsewhere, operates in one of two modes: arrogance or petulance. The American people were fooled by the Marxist Socialist Media into voting for someone whose presence in the office of president is worse than having no president at all.
With the election of Obama, the left thought that they had the American people fooled into subscribing to political and economic ideas that have been proven demonstrably false by the history of the 20th century. 50 million dead, and countless millions more living in pain and misery. Those are the wages of Obama's ideas. Those ideas are incompatible with freedom. Those ideas are incompatible with the truth.
Nothing will change unless we make it change.
