In situations in which a variable exhibits drastically different behavior in different groups, asking about the average may not be meaningful. After all, if we were to take averages, we would find that the average human being has about one testicle and one ovary, speaks mainly Mandarin and English with a bit of other languages thrown in, and lives in the middle of the ocean somewhere, where they probably work as a retail salesperson—somehow.
In the case of the raid on Trump's residence, this poll from Morning Consult and Politico suggests that opinion overall is divided: 41% of respondents said that the raid was an abuse of power that should be investigated, 40% said that it was not an abuse of power, while 6% said that it was an abuse of power that should not be investigated. Overall, around 47% expressed some degree of approval, while 37% expressed some degree of disapproval. As suggested by the statement at the beginning, 81% of Democrats thought the raid was due to evidence that Trump had comitted a crime, whereas 69% of Republicans believed that it was an attempt to damage his political career.
For another, albeit probably less reliable perspective, this article references a poll suggesting that Democrats mainly approve, Republicans mainly do not, and Independents lean toward disapproval. However, the source of the poll is given as the Trafalgar Group and the Convention of States Action, the latter of which is a right-wing group financed by the Koch brothers whose leader described the raid as a "gestapo-style injustice," so take that as you will. Presumably the first group, a relatively reputable pollster, performed the data collection and analysis for the latter.
