Obama released his first book to coincide with his first political campaign. And his second book 1 years prior to announcing his run for president.
Lessig is a reasonably charismatic speaker.
The rest I agree, Lessig is no Obama.
Look, I don't expect Lessig to make much of a dent in 2016. I wouldn't say he'll never make a dent. The only way TO make a dent is to naively keep trying, and learning, and being willing to look dumb in the process.
