But while Trump is losing, Barrett is winning. She's very likely to be confirmed and doing fairly well in the court of public opinion.
Beyond some disqualifying scandal for Barrett, the only way Democrats likely could stop her nomination is for Republicans to face insurmountable public pressure not to put her on the Supreme Court.
This net popularity of -10 point rating was the worst for a Supreme Court nominee since Robert Bork in 1987, who came in with a -11 point rating. Despite this low rating, Kavanaugh was still confirmed. Bork was attacked for conservative views by Democrats.
Still, that's a fairly important development given the polling prior to Barett getting named as Trump's nominee.
That 14-point split looked more like the polling that had Biden clearly ahead in the presidential race than the polling on Barrett now.
The average Supreme Court nominee since 1987 has run about 15 points ahead of the popularity rating of the president at the time.
Perhaps, Barrett's relative popularity wouldn't have been too surprising in the 1990s or even in the 2000s, when polarization wasn't as high as it is today.
But just before a presidential election in the year 2020, it's notable. And by being as popular as she is, Barrett seems to have shut off the last avenue opponents have to derail her nomination.
