Vladimir Putin is so confident going into Sunday's election, that he hasn't even bothered going on the campaign trail in the run up to the polls opening. There are a number of reasons why he can be so sure of victory - his high approval ratings and lack of strong opposition (this at least in part engineered by Putin himself), for example - but for many there is a big question mark over the legitimacy of Russia's elections. As Gallup surveys over the last few years have shown, even in Russia, those confident their elections are 'honest' are in the minority. Although the share of people trusting in the democratic process has increased since 2012, the results, as shown in this infographic, are rather damning.
