"Overall, do you strongly favor, somewhat favor, somewhat oppose, or strongly oppose the use of nuclear energy as one of the ways to provide electricity in the United States?"
There may be a convergence of liberals thinking he climate crisis needs a strong response and conservatives not knowing that and thinking they can still own the libs.
If you asked conservatives if they wanted to trade their gas stove for one powered by nuclear electricity you might get a different opinion ;-)
Carter outlawed the Plutonium economy, Reagan permitted it. Democrats campaigned to shut down the FFTF. Ralph Nader led opposition to new plants like Seabrook and Diablo Canyon. Business interests, then represented by Republicans, complained that nuclear power was regulated too much.
There have always been exceptions. Atomic Rod operated nuclear reactors in the land of submarines and was so impressed by the experience that he's become an evangelist for small modular reactors. He's a Democrat, even if he sees everything as nuke vs anti-nuke.
Also, 76% seems inconsistent with the 2022 Gallup Poll on the same issue (which gets 51% for the same question):
