No surprise Trump has never had a 50% approval on Gallup.Unlike Eisenhower,Carter,Reagan,Trump,Bush 1,Bush 2,Obama and even Joe Biden Donald Trump has never gotten the majority of the vote for President in his 3 elections. After a few weeks grace period Trump is headed back to where he left off in January 2021.
After a temporary bump in favorability due to Joe Biden being so bad Trump's favorability is headed back to where its always been.
And Trump supporters think he won a landslide victory with a mandate.Trump only won because millions of left wing voters like myself refused to vote for a 2nd Biden term.
