The Other Russia blog reports Garry Kasparov is out of prison. Kasparov leads Other Russia, a coalition of opposition parties aiming to surmount new institutional hurdles in next week’s Duma elections. He was arrested for protesting last week.

According to the blog, Kasparov says the arrest was a signal of Putin’s commitment to crack down if the opposition pushes back. But the former chess champ isn’t fazed; he’s writing an op-ed for the Wall Street Journal.
