Ukraine is imitating political competition along the model of modern Western Europe. But actually there is no political competition. The West will bring Poroshenko to power. In fact all frontrunners in the election would be acceptable for the West, as they would do as they are told. But Poroshenko has advantages, as he has already proven himself. If he wins the elections, it is obvious that it would happen with great violations. Just look at the millions of Ukrainians that cannot vote. These elections have nothing to do with democracy.
Conspiracy theory with no evidence given. Consistent with recurring pro-Kremlin disinformation narrative on the presidential election in Ukraine.
The election will not be held in the territories that are not under the control of Ukrainian authorities. According to the Ukraine's Central Election Commission presidential elections will be held in 12 out of 21 districts in Donetsk region, as well as in 6 out of 11 districts in Luhansk region, while the elections in the Autonomous Republic of Crimea and the city of Sevastopol, which are occupied by Russia, will not be held at all.
