Biggest thing against nuclear power is the cost associated with it. Other, sustainable sources of energy like wind and solar, combined with hydrogen and batteries, are way cheaper due to their simplicity. Thorium reactors are a nice idea but need so much development (costs) that they will take a while to become a reality, if ever at all. Probably nuclear fusion will be available sooner than thorium fission for power generation, which also needs decades of development. And then there’s still the problem of nuclear waste. Maybe not a huge problem, but still one without a viable solution.
What I didn’t see in the reactions yet is that a lot of Americans do not want any government involvement at all. Save for things that are supposedly written down in the Bible. The Republican party is providing just that, anti-establishment, anti-intellectual and don’t forget: anti-minority. Just people being tough and dare to support the party who will turn the clock back to when times were perceived to be better. Same sentiment is present in Europe by the way, like it was a century ago.
