I’m sorry - it wasn’t really rude though, was it? It’s pointing out the absurdity of what he’s claiming to do. Sounds good, but just pretty empty words.
And as for this:
Improve services and infrastructure for existing and new residents, prioritises education, social care
Undoubtedly this sounds laudable, but how is he planning on doing that? Anyone could make those claims. A fully costed plan of action is more important and impressive.
