This “Sundance” guy/gal is well informed, it would seem.
The truth is pretty much 180 degrees back-asswards: Felt - playing the McCabe role - was driving the story-line, and using W&B as his publishing conduit via the Wapo.
So, if you're a bright guy like Trump, and you want to reprise the style, and dramatic, slow reveal of Watergate, how would you go about it? Why, copy the original of course.
So, rather than Sundance being some kind of pioneering investigative journalist, in actuality we probably have someone on the Trump team playing the Felt role (with Trump's knowledge and approval as part of an overall public 'softening up' campaign), and using CTH as their Wapo.
The alternative is some random, brilliant guy is just out their crunching the numbers, doing the detailed research, and then pulling it all together in a real-time, highly organized and methodical manner. You know, sort of like W&B were "brave" investigative journos. LOL
