I must first repeat my ongoing complaint, why are the Independent Scone Conservatives allowed more than one policy, and one that isn't even scone based? This is clear electoral fraud.
Depth of character is indeed a very suspicious thing to find in a potential councillor. They are supposed to be basic non-entities that serve almost entirely as popularity points for the national parties. Barely anyone votes in local elections and most don't know who their personal councillors are. And, to some extent, it makes some sense outside of cities. UK is very centralised after all.
On Collridge, can you clarify which of the 57 variety of inter-war Liberal he is? Liberal, Independent Liberal, National Liberal, Liberal National? What are his views on Scone Tariffs? Is he one of those Scone Free Trade heretics? Such madness will see the country flooded with inferior subsidised German pumpernickel, mark my words.
Entirely possible he's just a nice man with a clever idea. Those tend to crop up quite a lot in the inter-war period too, and by and large were criminally underused by the British.
Being an American (colonial to you pompous windbags),
Vague, more like. The Americas are absolutely gigantic continents with many different countries and cultures housed within. Even if we were to assume you were from the US, that's still a continent-wide, if fortunately non-continent short nation.
