The Republicans have waged a war against science in the last few decades, and it has had some success. The confidence in science among the Republican base has dropped from 72% in 1975 to about 45% in 2021 -- a huge drop of 27 points.
The drop among all adults was only 6 points, and Democrats showed an increase in confidence in science of 12 points.
