It does matter how you campaign. Very few people live without access to information beyond the price of milk. If you see that global inflation is a thing and that it is a topic of importance for potential voters you could acknowledge that it exists and work on your messaging/make it look like you're trying to do something to fix it.
The messaging that really gets through to people who can't understand that is naked, blatant lies. It worked with Brexit, and it worked yesterday.
