Russia has scheduled its next presidential election for March 2. The current President, Vladimir Putin, isn't allowed by the country's constitution to seek a third consecutive term in the office. Four candidates were approved by the Central Election Commission on the 27th of January. Andrey Bogdanov, a Russian politician, Mason, Grand Master of the Grand Lodge of Russia and Chairman of the Democratic Party of Russia, is one of them. He began his political career in 1990, when he joined the Democratic Party of Russia. Bogdanov is known as a fierce advocate of Russia's integration into Europe. His party failed to make it into the State Duma in the December 2 parliamentary election, gaining only 0.1% of the vote. And yet he somehow managed to collect the two million signatures needed to register as an independent candidate for the presidential election.
