You know, there is a link in the article to the poll itself. You can actually read it instead of guessing at what nefariously biased questions it asks. 
Interesting how you're assuming that I'm assuming. I did read the poll, and even if it were a perfectly sensible, objective poll, there still would be no reason for the authors to describe its findings using right-wing snarl terms like "identity politics" or casually present the misinformation their respondents expressed belief in as fact. But of course the poll is neither sensible nor objective. To look at just a couple of questions here:
Please indicate if you agree or disagree with the following statement.
Joe Biden and Democrats in Congress are out of touch with hardworking Americans. They have been so focused on catering to the far-left wing of the party that they’re ignoring Americans’ day to day concerns, such as addressing the rising prices for goods and gasoline and combatting violent crime.
This question is ludicrously loaded. Good, reputable polls don't just blatantly spell out a narrative using this kind of partisan language and somehow maintain their neutrality by simply including the option to disagree. The question also takes it for granted that "catering to the far-left wing of the party" is a negative - the respondent is only asked if it's what they think Biden is doing, not if they think that Biden doing it is good or bad.
Do you think President Biden and the Democratic Party should move more to the left and embrace more liberal policies, move more to the center and embrace more moderate policies, or do you think President Biden and the Democratic Party should stay where it is right now?
This question, meanwhile, indicates their expected answer to the previous question, because here they are taking it for granted that Biden and the Democrats are already on the left, a claim that, regardless of anyone's opinions of the merits of being on the left, is objectively just untrue. Biden is not a leftist, he is a centrist, and there's no indication that more left-leaning Democrats have any real influence over his agenda or the party's as a whole. The notion that the Democratic Party as a whole is trending far to the left is yet another right-wing lie that conservatives are repeating as much as possible to gaslight the rest of the country into thinking that Democrats should in the interests of fairness move further to the right. And no matter how many concessions Democrats make or compromises they offer, Republicans continue to drift further and further into extremism while their stooges in the media keep up the chorus of how Democrats are so unfairly devoted to the left. This poll/article is just another example of that. Don't fall for it.
