The RNC doesn't have a platform in 2020 so we can't speak of a defined Republican position on individual issues anymore. In their previous platforms, they supported expanding nuclear: http://ansnuclearcafe.org/2012/09/18/the-party-platforms-on-...

The article states that the Republican Party is pro-nuclear and anti-government, and the Democratic Party was anti-nuclear and pro-government.

While it seems from the headline that both parties are now pro-nuclear, it is unclear how that will play out at a policy level. Based on the quoted stance of being "technologically-neutral", it may well be the case that Democrats still won't support nuclear power, not because they are against it as a rule but because they see solar and wind as being superior alternatives.

A bit meta, but as someone from Europe where the countries aren't usually divided into two opposing camps, this seems oddly phrased to me. Could someone from the USA who considers themselves either neutral or a democrat comment on whether "just the Dems" sounds negative to you?

It doesn't sound negative to me at all; just a factual way of stating that the policy is only supported by one party. Perfectly normal figure of speech here in the states.

If the Democrats are for it, then they are against it.

The Republican Party has been pro nuclear for years...

Yeah, and they were anti-Russia, for small government and personal responsibility. The GOP isn't what it used to be. I have no idea where they stand on anything and even if I did, I wouldn't bet that it's the same tomorrow.
