The devil is in the details

News Flash: Biden is polling at 59 Percent Approval Rating - from Pew Research Center:

Biden Nears 100-Day Mark With Strong Approval, Positive Rating for Vaccine Rollout
Joe Biden approaches the 100-day mark of his presidency with a relatively strong job approval rating and the public continuing to express positive views of the coronavirus aid package passed by Congress last month.

Stuff - and then the money shot:

Currently, 59% approve of the way Biden is handling his job as president, while 39% disapprove.

Them's the numbers - like it or not. But wait...  This is a long document.  Seven pages. Scroll down to page seven:

So, your sample was 5,109 of which 33.39% were Republican or leaning and 63.67% were Democrat or leaning.

Bias much?

I would call that busted.  Totally and unequivocally busted. Busted with a side of fries and extra tarter sauce.
