See the Australian conservative opposition (Liberal and National parties), for example. They are bought and paid for by the fossil fuel industry, have no actual plan to roll out nuclear, but are using it as a delay tactic. See also how conservative parties are attacking renewables but not directly talking about coal (for the most part) because they know that the general public won't accept it anymore. Conveniently, attacking renewables and talking up nuclear is an easy way to keep coal around for a little longer.

Your points are more historical, I'm talking more about the last few years or so, the period where most conservatives now won't admit to being climate change deniers, but incidentally have positions that worsen climate change.
