A quick check shows that it seems really unlikely that the wording is incorrect...
Questions - Racism in Politics - July 15-16, 2019 - Rasmussen Reports®
I didn't see the poll questions linked on the Rasmussen page that was linked in the article, so thanks for finding that.
As has already been pointed out, there are some potential issues with the poll. For one, without the answer options (and a subsequent breakdown of results), it's hard to interpret. That's not a black-and-white question - there are shades of gray. It certainly
can be racist, but it's not
always racist. If the answer options were simply yes/no or agree/disagree, then the question is absolutely flawed. And if they had other answer options but counted the "sometimes/it depends/maybe" responses as "yes" for reporting purposes, then they did fudge the results.
Second, the analysis is skewed - the article in the OP makes it sound as though the respondents are saying that it's
always racist for a white politician to criticize the political views of a black politician, but that's not what the question was asking.
Going into the other questions, the first one is poorly worded so as to create a false dichotomy. Trump being a racist does not preclude his political opponents using that against him (and vice versa). The third question, while interesting, also makes the poll's bias pretty obvious. The "reverse racism" idea has been a right-wing deflection for a long time now, and while it does have some merit in that racism can go both ways on a personal level, it's not really relevant to the discussion of racism in the US, which is more related to
institutional racism.
If you're surprised by the results....I gotta ask why? If people buy into ideas like white privilege, white fragility, whitesplaining and other "newspeak" terms that are mainly a part of left wing racial dialogues (you simply don't see the right talking about these ideas except when pointing out their flaws)....this is the logical conclusion.
Why wouldn't they believe that it's racist to criticize non-whites' political views? Or is it just startling to see such a large portion of the party believe in something so clearly racist?
I find it surprising because I don't see the left talking about those terms either - apart from white privilege, but not in the way that you view it. This forum is literally the only place I've ever seen the term "white fragility" mentioned. Those are very much fringe views. While I have no doubt that there are people who believe that it's always racist for a white person to criticize a black person, I can't see how they could make up a full third of Democrats based on my own interactions with members of my party.
