It was billed as 'All About Trump'. But in recent historical context, the US 2020 presidential election was a pretty normal battle of Democratic and Republican voter bases. The combined vote percentage of the two main parties was about 98.3%, similar to 98.3% in 2012, 98.6% in 2008, and 99% in 2004. The outlier was 2016, when Democrats and Republicans combined for only 94.3% of the total vote.
