The sentence that you snarkily attempted a grammatical correction on, does not contain a grammatical mistake. Considering the text of your comments contained in this exchange, with the sparse attempts at employing correct grammar, I'd recommend against attempts at grammatical correction like this in the future. Since it is not clear that English is your first language due to your poor grasp of my comment, the sentence in question contains "it" in reference to the circumstance of the death, as an object of the verb "believed", not the person of Epstein. The phrase "it was murder" is a complement to the verb "believed", meaning that subject of "Democrats, Independents and Republicans", had an belief that what occurred (it) was murder. Also, the percentages I mentioned, which were cited in the linked page, do not represent the split along political lines, but represent a separate percentage for each, as I said. Since you also don't seem to recall elementary arithmetic, 40% + 32% + 33% = 105%, not 100%.
