This is Ukraine today, at least as seen by most Russian news media: the government is run by anti-Semitic fascists, people killed in protests were shot by opposition snipers and the West is behind it all.

And the room to disagree with that portrayal is getting smaller by the week.

With Crimea set to hold a referendum Sunday on whether to merge with Russia, the push to demonize Ukraine’s leadership has reached fever pitch. Authorities in Ukraine have responded by blocking Russian TV channels.

Lev Gudkov, head of a respected independent Moscow-based polling agency, says the propagandist tone of Russian state television has reached new levels.

“For intensity, comprehensiveness and aggressiveness, this is like nothing I have ever seen over the whole post-Soviet period,” Gudkov said.
