If Hillary had won, Garland would have not been on the Supreme Court because she would have nominated someone else.

If Hillary had won, Garland would have not been on the Supreme Court because she would have nominated someone else ^worse.

. . . but note well, Trump provided a list of dozens of potential SCOTUS nominees. That meant that he was not specifically committed to one in particular, but, OTOH each one represented a target whom the Democrats could use to discredit Trump:

"See, if you vote for Trump so-and-so will be on the Supreme Court.”

But the Democrats defaulted on that possible target. And note well Hillary did not put out her own list.

I for one voted Trump because, first, the alternative was Hillary, and second, Trump promised the nomination of a SCOTUS justice whom knowledgable conservatives respected. Many other voters voted Trump only because of his SCOTUS nomination pledge. Trump won. Hillary didn’t. Trump’s nomination cannot be seriously described as "out of the mainstream.” Anyone making such a claim is out to lunch.
