FWIW, the novels have explained that every Federation member selects its councillor however they want to. Betazed's is chosen by popular election; Andor's, by the majority party in their Parliament; Bajor, by the First Minister (with confirmation by the Chamber of Ministers); didn't say how Earth chose theirs, although I'd guess it's the same as Bajor's (the United Earth Prime Minister chooses, and the Parliament confirms).

Only a tiny fraction of Trek fans even read the novels, and there is no reason to consider their content to be canon.
I really could give a damn about what is canon and what is not. No, actually I couldn't give a damn, no matter how hard I tried.
