Actually you couldn't be more wrong about that. She is actually the least divisive nominee since Justice Roberts nearly 20 years ago.
Justice Ketanji Brown Jackson has both substantially higher approval ratings and substantially lower disapproval ratings of any recent SCOTUS nominee.
According to Gallup which conducted the polling:
Far more Americans approve of her nomination, and far fewer disapprove of her than any of Trump's three nominees, and by wide margins of 10+ points or more. Here are the actual numbers:Initial public support for judge Ketanji Brown Jackson's confirmation to the Supreme Court ties as the highest Gallup has measured for any recent nominee. Fifty-eight percent of Americans say the Senate should vote in favor of Jackson serving on the Supreme Court. Only current Chief Justice John Roberts, at 59% in 2005, had a level of support on par with that for Jackson. Most other nominees had support in the low 50% range, with five below that mark.
