Like you he claims to be pro-nuclear but is also scathing about government subsidies and expensive power. Which doesn't add up, not for two decades if you're paying attention, and certainly not for the last five years even if you haven't. Renewables are cheap power.
It's like his audience is a couple of decades behind the facts if they can accept this as a logical argument.
His very pro natural gas stance is also a weird anomaly.
