He is a Russian Nationalist, he supported the Annexation of Crimea, the Russian invasion of Georgia and the uprising by ethnic Russians in Ukraine.There's a world of difference between populist, and a people's representative. He has always been anti-corruption.
It is true that he appeared to have been found guilty of crimes of embezzlement, but EU, and others within Russia (including Gorbachev) consider them to be politically motivated convictions to stop him being eligible for political positions.
It is also true that he did harbour nationalistic preferences, and may still do so. He nay even still have concerns about different religions. But he is only 44 years old, and has come a long way in his 'wokeness', only recently speaking out in support of BLM.
Although having said that, if i was Russian i would also support all the above.
