I think Trump used the word “wiretapping” deliberately.....b/c it’s embedded w/ the most ominous connotations.
It can also be interfaced w/ other ominous terms......like the scary word “surveillance.”
I agree, the connotations were key. Wiretapping suggests Watergate immediately.
And “wiretapping” is the kind of word that connects with deplorables (man-on-the-street) talk, meaning it can go viral as people talk on the subway or at work.
All the stuff that the Dilbert guy says about crowd psychology is second nature to Trump and his dark and lovable Rasputin, Bannon. LOL!
