Volodymyr Zelensky’s presidential term expired on May 20th

That seems like a pretty weak excuse for cancelling the election, especially given that it would effectively be a referendum on whether to continue the war or not.

But there are some logistical difficulties involved in holding an election in a country currently being invaded, especially with the invasion being broadly successful.

The point here is that if fighting Russia was a popular opinion in Ukraine, then the government would win by a landslide.

Would that be the same 20% of Ukraine that was in civil war with the rest of Ukraine after the coup in 2014 by any chance? Meanwhile, even western media admits that Putin has massive popular support https://time.com/6977473/putin-opposition-movement-unity/

That 20% has been liberated from the fascists Ukrainian state that was trying to ethnically cleanse it. They want no part in its elections.

Russia did hold elections and is "liberal democratic" but Russia has hardly been turned into a warzone in the same way. There are probably other examples worth citing.

20% of Ukraine is currently occupied by a hostile foreign power. 0% of Russia is occupied.

Also, Russian elections give whatever results Putin wants, so the status of the electorate doesn't really matter in the first place there.

Last I checked, Russia held elections, but I guess cancelling the elections aligns closer with western values.

There's extenuating circumstances! 

You're anti-democratic.

There may be extenuating circumstances..
