i dont know,
i dont think what kaguya;s doin is the same as what she do to other elective.
since she says something about "you dont have to worry about their enthusiam infecting other" which is actually a good thing for kaguya if their "enthusiasm about shirogane" do infect other.
in fact,
i think what kaguyaactually want was to make the news club be neutral about shirogane, since, just like the news prez said, the mass media club backing prez directly or indirectly will cause problems in the future (just like how hongo suspicious about shirogane's high support despite he is an impure)
