In the U.S. the president at the moment got to decide how we'd respond to the pandemic as it happened. Lots of people disagreed. They got to vote in a new president, but that one vote is for a whole basket of issues. Not exactly a referendum on the pandemic, more like a decision on which faction/ideology will be in control of the federal government until the next election. Calling the pandemic response a democratic decision seems like a bit of a stretch to me.

I'm sure the situation is the same in many of the elections that you linked, most countries are republics, not democracies.

Admittedly I wonder about the modern use of the word "democracy" being used to legitimize what was supposed to be a republic, was never meant to be a real democracy, and has drifted into being a plutocracy.
