Donald Trump has already appointed three Supreme Court justices. In his second term, he could well have a chance to name two more, creating a high court with a Trump-appointed majority that could serve for decades.
The decisive outcome spares the court from having to wade into election disputes. It also seems likely to change the tenor of cases that come before the justices, including on abortion and immigration.
The two eldest justices—Clarence Thomas, 76, and Samuel Alito, 74—could consider stepping down knowing that Trump, a Republican, would nominate replacements who might be three decades younger and ensure conservative domination of the court through the middle of the century, or beyond.
