I'm constantly arguing with my 3 ultra liberal brothers over politics. When the shouting matches simmer down I tend to always rely on posing one question to them that leaves them in a state of silent stupor. That question is "can you name a single accomplishment of Obama from his first 6 years in office?"
But I help my tongue-tied brothers out by telling them that Obama's one accomplishment (and one that cigar banks his entire presence here on) is that he (Obama) was and still is an excellent campaigner which in the long run gave him back to back wins for the presidency.
But as far as citing a legitimate American based and productive accomplishment as a leader in world affairs or as a leader in growing our anemic economy via jobs or via investment in our people or in our businesses he has simply been a complete failure.
