Or is it so obviously a nothingburger that investigating it will show zero criminal intent, nor illegality??
dems are in a no-win situation. if they declare it a nothingburger and do nothing, GOP will claim a double standard, political persecution, etc. if the dems take it seriously and attempt to show the same rigor as with trump (i.e. the path they've chosen), the GOP will seize this as proof of biden's corruption, untrustworthiness, etc and will hammer biden for the next two years with it (RE: mccarthy has already stated that congress will "fully investigate" this matter).
reminder: the GOP playbook holds that an accusation is all that is needed. the outcome of the investigation doesn't matter. only the guilty are investigated, right? RE: trump & guiliani demanding that the ukrainians announce an investigation into biden, in 2019. they didn't care if an actual investigation took place, they just needed the one-time headline to "prove" that biden was corrupt... why else would a sovereign nation investigate him???
so cynical.
