I think the parallel is with Lib Dems, albeit in the other direction: they're seen as competent at a local level, but not trusted in national government.
Cognitive dissonance isn't an impediment for anybody who can look at Farage and think him suitable for election, so my prediction is that future voters will revert to electing traditional parties to local government, but Reform to national: this early foray into bottom-up control will be largely forgotten.
But a periodic reminder that Reform is elected not through overwhelming support, but because the 70% of the population repulsed by it can't find a way to work together.
