Believe it or not.
Five recent surveys have indicated strong support for President Joe Biden's decision to nominate Jackson for the Supreme Court seat retiring Justice Stephen Breyer is vacating. According to an average of polls by Gallup, Fox, Monmouth University, Quinnipiac University and the Pew Research Center, about 53% of Americans supported her confirmation, with about 26% of Americans opposed. This is good for a +27-point net popularity rating.
If Jackson's ratings hold up through her likely confirmation, she would be the most popular nominee to be confirmed since John Roberts in 2005. Jackson's popularity should only help her in the confirmation process.
A few years ago, I built a statistical model to help understand why senators vote the way they do on Supreme Court nominees. The model took into account variables such as a nominee's qualifications, the ideology of the nominee and the senator, etc.
One of the factors I included was public sentiment about a nominee. Holding everything else equal, nominees got more votes when they were more popular with the public. Clarence Thomas, for example, was generally viewed in 1991 as very conservative and not as well qualified as many earlier nominees. Yet, Thomas was confirmed by a Democratic-controlled Senate.
