That would be exactly what people would suggest, because they know from experience the "blowhard from marketing" will screw things up so badly, that the only viable option will be to start over with a clean slate. And that's exactly what's needed for a "large software project that was going awry" but it's always easier to say patch this here, tweak it there. Only when you can no longer patch and tweak yourself to anything functional will people actually clamor for a clean break.
That's why they vote for Trump. Nobody expects him to fix anything. They expect a clean slate at some point. Whether it's during his tenure or after, it's irrelevant. He's the catalyst.
