2017 to 2025 approval or not djt vs biden

Graph tracing the changes in favourable & unfavourable views of trump from 2017 to 2015 [#45 / #46 and now #47].
I find it astounding that djt's "dis-approval" rating rarely dropped below 50% over those eight / nine years, and his actual approval rating rarely topped 45% in the same period.
