Why don't Democrats run moderate candidates in red districts?

Here is a campaign website for a Democratic candidate for Wyoming at large House of Representatives districts:

My question is: why do Democrats think running such campaign would help win in a state that voted 70% red?

There are of course MAGA Republicans running in deep blue states as well (I can think of Dan Cox in Maryland in 2022) but I get the impression than Republicans run more moderate candidates in hard races, than Democrats do.
