If he were an unknown or a candidate with a decent track record, yes. But his negatives are such that all this info is useless in overcoming his core failures.
He would literally have to ‘custom threaten’ exposure of this personal info for every person there’s data on. Otherwise, a pile of info on your shopping habits at Target aren’t going to help overcome the reality of the O admin.
His real problem with that is he’s getting called out now on the fact that all he does is political. If he has to send out a dozen different ‘messages’ at some point his hypocrisy will show out in the conflicting nature of his pitches.
