MOSCOW – Tonight is the first night without protests here since some 6,000 young people gathered Monday night to express their frustration with the electoral fraud in Sunday's parliamentary elections and, more broadly, the institution of Putinism. They came out again Tuesday night, where they were met by thousands of drum-beating pro-Kremlin youth activists. And again on Wednesday. Nearly 1,000 people were arrested, and many of them -- including anti-corruption blogger Alexey Navalny, a political rising star since he coined the phrase "Party of Crooks and Thieves" to describe Vladimir Putin's ruling United Russia -- are still in jail. Moscow is filled with tens of thousands of extra Interior Ministry troops and armored personnel carriers, and the city's skies crackle with the sound of helicopter blades.
