That's kinda how democracy works y'know... if someone got elected and everyone just went "oh well, they're doing their best," then there'd never be a change - we'd just stick with the same inept leadership. The party in government should absolutely be questioned on their decisions.
The fact the strongest argument the Boris Johnson fanboy has is that all politicians would make a balls up of leading the party through this speaks volumes.
And it's more than a little strange that someone perceives a political persuasion to be a fetish too.
