These polls don't mean much.

First term approvals:

GWH Bush 60.0%, lost a 2nd term.

Bill Clinton 49.6%, won a 2nd term.

Barack Obama 49.1%, won a 2nd term. [Many forget how bad the Obama years were. They were considered a Second Great Depression era. High inflation, etc.]

the difference this time is that first of all Biden is polling much worse than those AND more importantly Biden is running against an incumbent not an unknown. People can make a side by side comparison of which president they liked better Trump or Biden. All the advertising, debates and ads in the world wont change anyone mind who has already decided that things were better when Trump was president.
