They've been very consistent. They ram through whatever the Heritage Foundation (boy, if there was ever a truly evil org with a misleading name) tells them to. That's how they got selected. Heritage literally gave Trump a list of acceptable names, all members.
“There was obviously overlap between the Supreme Court list that Heritage put out, which I compiled and which was available to all the candidates who were running, and the list Donald Trump put out,”
They really are congratulating themselves on Federalist Society's work. Leonard Leo was the one working the list.
