Brexit relied on being everything to as many people as possible. They never made any one specific promise, you could vote brexit if you hated immigration, or hated the alleged bureaucracy (it's not that big), of feared for an eu army, or turkey joining, or you wanted to wave a st george's cross or you hated political correctness etc etc.
TRAs are the same. They cannot actually specifically define what they believe or what they want. They rely 100% on vagueness and never actually saying anything concise and definitive.
Maybe this is obvious, but it just occurred to me.
