How is that even controversial? We all watched it happen in real time.

Harris hit the ground running and she and Walz barnstormed the country with an overtly populist message and it worked - they immediately started catching up to, and even passing Trump. There was a moment there when it looked like he was dead in the water - that nothing was going to stop Harris/Walz.

Then the Dem power brokers reeled her in and, however they managed it, got her to drop the populism and switch to mealy-mouthed, pro-corporate neoliberalism, and it was all downhill from there.

It was just that simple and anyone who was paying attention at the time could see it as it happened.
