Recall that last quarter he set his sight on the manipulated US stock market, and HFT traders in particular:

"The other day I was watching the stock open up, and it went up on share volumes of a few thousand shares. I mean, every trade was a tick up. That's not the way it should operate in an honestly or intelligently run exchange.   But that's the thing, all those guys sold their dark pools and their order flow and the positioning on the floors of the servers to the HFTs. And it's made a couple of guys that I'm friendly with very rich because they are high-frequency traders. But I don't respect the activity, and I'm severely critical of it. And don't mind saying so, either."

This time, during the July 28 Q2 earnings call, the 74 year old billionaire chimed in on the most important topic for the US economy over the next 4 months: the presidential election, and - in typical brutally frank fashion - he cuts right to the chase. Here is the key segment, with our highlights, responding to a question on what to expect from the US election.
