I was going to write this up, but Bayou Renaissance Man already hit the thing out of the park.
"Hell yes, Donald Trump was "wiretapped.” So were you, by the way. And me. From open source information shared by defectors the intelligence community was too incompetent to keep from defecting, we know that every single electronic communication we send is collected in the NSA mainframes. Every single one. And the NSA has algorithms they can use to search it. You don’t go plant a bug in Trump Tower. You wiretap the opposition party’s nominee for president by running a search through the communications that the government “incidentally” collected. And if you find something juicy, then you call up your buddy at the Post and hand it over."
