Jake Tapper is shocked that Barack Obama lied about cigarette smoking. If we can trust Tapper’s “unusually keen sense of smell” as much as he does, it is possible that Tapper caught Obama at a time when he fell off the wagon but denied that he smoked.
If he thinks this is worth writing about, Tapper’s sense of people is not as good as his sense of smell. He needs to watch House. As Gregory House repeatedly reminds us, patients lie. For that matter, everyone lies. While there are many aspects of House which are totally unrealistic, in this case Dr. House is correct. I would not be the least bit surprised to hear that somone attempting to quit smoking might both fall off the wagon and lie about it.
This is hardly an example of a character flaw which would affect who I vote for. On the other hand, if Obama had admitted to smoking but also claimed he had to dodge sniper fire while doing so, it would be a totally different matter.
