It's reasonable to at least expect that. It's their job after all, while for any single voter there is a lower standard you can realistically hold them too and less time available to verify/debunk claims.

On top of that, there are also instruments that help the voters track whether politicians are engaging in corrupt lobbyism like voting records + donation / campaign contribution records, though few countries do that to a degree that it forms a cohesive anti-corruption framework. None of those measures exist for individual voters.

Why is it reasonable to expect that? What mechanism makes politicians immune to disinfo?

Well, your local coucilor probably doesn't have access to it, but MPs definitely have access to aides and experts they can ask for opinion and summary before they go in front of a camera and make a fool out of themselves for saying something based on a snippet they saw on TikTok. They are literally surrounded by people whose entire job is to be well informed.
