For action shooters using high shutter speeds, the SLR blackout time is trivial and unnoticeable. Think about it. Movies display a still image every 1/24 to 1/30 second. Yet our minds connect the still images together. Our minds manage the same feat when panning in burst mode. Admittedly I can only state from personal experience the effect of 1/500 to 1/8000 sec at a burst rate of 6 per second, for birds in flight.
As for the US presidential election, it has the morbid attention demand of a highway crash that you crawl past in a traffic jam.
In your guts, you know he's nuts!
