"Run, Lawrence, run!" That's the blog comment that Stanford law professor Lawrence Lessig received after a brief mention of Congressman Tom Lantos's retirement. Could he? A Daily Kos blogger thinks it's plausible, and a majority of readers polled say they'd vote for him. Lessig is intensely popular in Silicon Valley's geek-thinker circles. But he's a virtual unknown among most voters in the South Bay district Lantos represents. Still, Lessig stands a chance of boosting his profile by tackling the issue of corruption — not the tired political charge, but the larger systemic issues that underlie the rot in our political system. He will deliver a speech on the subject this Thursday. If he has intentions to make the law, not just study it, then that occasion is as good as any to announce a run.
