John Roberts pulled an impeachment bait and switch in his immunity ruling
MSNBCJUL 2024
SCOTUS' ruling was not based on legal precedent or thoughtful debate between conservative and liberal justices, but rather an explicit attempt to turn future far-right presidents into dictators. Given the court's super majority of pro-Trump justices, coupled with its current status of life-time terms and lack of an ethics code, the only way to reign in their power and that of their friends in government is to codify a new law banning such ludicrous legal theories.
The Democrats are projecting their nefarious goals with respect to SCOTUS onto the Republican Party. The court's ruling was a very mild one that simply asserted the right of president's — and not just Trump, but all presidents from either party — to govern without fear of being prosecuted by their opponents after leaving office. The Democrats don't want to reform the court—they want to completely redesign it to give themselves absolute power over the country.
There is an 8% chance that there will be any change to the composition of the Supreme Court in 2024, according to the Metaculus prediction community.
