PUTIN'S DEMOCRACY

  MOSCOW — Russian opposition leader Alexei Navalny was wrestled to the ground and forced into a police vehicle Sunday as he headed to a Moscow protest that was part of a day of nationwide demonstrations.
    Navalny, the most prominent foe of President Vladimir Putin, organized the protests to urge a boycott of Russia’s March 18 presidential election, in which Putin is sure to win a fourth term.
   The anti-corruption campaigner was denied permission to be a presidential candidate because of an embezzlement conviction in a case widely seen as politically motivated.
