From the BBC news:
"Legal experts say Judge Cannon's ruling is likely to be overturned but that the further delay to the case could prove beneficial to Trump's campaign.
"Her ruling has no chance of being sustained on appeal as it conflicts with decisions of the Supreme Court and other lower courts, but it will have the effect of preventing any more embarrassing revelations before the election," said David Super, a professor at Georgetown University Law Center."
Unfortunately, the Supreme Court justices appointed by Trump appear to have no problem in reversing what was believed to be established law; for example Roe v Wade.
And if Trump gets elected, the likes of Thomas, Alito and possibly Roberts, will likely be persuaded "to seek" retirement from the Supreme Court, but will then take well paid directorships at some business run by one of the billionaire backers of Trump. - Thomas in particular appears to enjoy a lifestyle that his salary of $280,000 cannot provide.
That will leave Trump with two, possibly three posts to fill with much younger even more right wing justices. Barring some very unexpected turn of event/s, that would leave the newly appointed justices, together with Kavanaugh (born 1965), Coney Barrett (born 1972) and Gorsuch (born (1967) to oversea law making in the USA for many years to come.
Edit. Yes, I was aware of what legal experts say and addressed above. My concern was addressing two statements which prima facie were peddling bullshit.
