The President says he wants Supreme Court justices who will interpret the Constitution as it is written, not according to what they wish it says. It’s a good speech line, but I don’t think the President really means it.
People on the Left generally assume that “strict construction” is Right Wing code for overturning Roe v. Wade, environmental protections and the like. And indeed it is. But it’s also more. Ideologically the doctrine cuts both ways, because “judicial activism” has cut both ways. It was a blatant act of judicial activism, for example, that took the protections of the Bill of Rights, which Jefferson et al intended for real people, and extended them to artificial persons called corporations.
