2018 was 49% average for the country. One of the highest in decades, primarily driven by dissatisfaction of the Trump administration. I’m going with lower than 49%, but not as low as 2014, 38.5%. I’ll say 43%.
54%. This will be a wild outlier.
I’ll say 43% as well, with the drop from last time being driven mainly by the decrease in the 18-24 sector mentioned in the OP’s link.
