Greg Palast is a brilliant journalist who has meticulously documented voter suppression for decades. All his books are relentlessly factual with links to primary materials and sources.

I haven't read Armed Madhouse, but I assume it's similar to "The Best Democracy Money Can Buy", where he documents voter suppression in obsessive detail, and notes without comment how the number of votes provably suppressed is significantly less than the margin of victory.

Maybe instead of mockery, you should actually read his books.
