If I may:
#1 Biden isn't "doing badly" because of approval ratings. Approval ratings are bad because Biden is doing BADLY.
#1A - Example: Within hours of taking office, Mr. Biden signed an executive order revoking the permit for the Keystone XL pipeline destroying roughly 70,000 American jobs whilst simultaneously thrusting the USA into a need to purchase vast amounts of foreign oil AGAIN. Does one need PROOF of how this action has hurt America? Simply go look at the mark-up of gas prices at the pump since Biden was "elected".
#2 Trump gave inspiration to Americans by showing a BACKBONE, and instead of broadcasting any and all ACTIVE military intentions in advance as Mr. Obama did, Trump said during his first state of the Union address that energies of that nature were coming to a STOP. Trump also energized the signalling that the days of America (figuratively) bending over for another kick in the bottom had met a line in the sand with him.
#2A - Example and case in point: Trump (figuratively) crammed his pinky finger up Kim's nostril and essentially said: "Look here punk, you continue with your non-sense and threats to America and our allies, and there won't be a bunker DEEP ENOUGH for you to hide in, so GROW UP and play ball with the big kids, and we'll all get along.. And guess what? KIM needed this spanking and to be INVITED to the big kids table, and it worked. But where are we today? Back to the way things were during Obama's reign.
#3 Liberals screamed and raged that Trump was going to cause WW3 in the Middle East.
#3A - Trump was nominated for THREE Nobel Peace Prizes for the work he accomplished to UNITE the Middle East.
etc etc etc etc etc..
