In his time ,president Harry S. Truman was also a lowly rated president by the masses, but yet pulled off a miracle win in 1948. Today he is highly regarded for the long term goo he did for the country in setting up the foundation for containing Russia and interrogating the armed forces. Moreover, there has never been a more honest president, right down to making sure that he never used stamp paid for by the government for personal matters--the extreme opposite of Trump.
Today, no one understands foreign policy and how the mechanics of government work as well as Biden, BUT he is looking frail. Let's hope he can hold it together, else the Donald will lead the world over a cliff.
