I think his record of little accomplishments as a congressman illustrates that he talks a good game, but doesn’t produce. And as you mentioned, he said he would do certain things, or more precisely, abstain from certain things, and then he didn’t. Having ideas or intentions, or paying lip service does nothing for constituents. Unfortunately, aside from the creepiness aspect of the twitter debacle, he demonstrated his true character that he will say anything, but that doesn’t mean he will do anything. And yes, that makes him a good politician, because a good politician will talk themselves silly to get votes. However, that doesn’t make him good leadership material.
