I'll address the TikTok piece since that was mine... the TikTok thing isn't a Dem talking point... if anything, GOP politicians, to their credit, actually take the security risks from TikTok more seriously than most Democratic politicians do.
But my bringing it up doesn't mean that I believe it is silly to take the balloon thing seriously, it means that I consider the proliferation of that app far more concerning than the balloon. And, by extension, wish that the media would give even one quarter of the attention that it has given this incident toward that particular issue.
