Why should he "honor her dying wish"?
I don't recall anywhere in the constitution which states "If a supreme court justice says they want a new president to replace them then this must be honored."
Also let's stop with the fuckery already. We have been hearing for years from people such as yourself that Trump and Republicans are "tearing this country apart" and it's been pretty obvious who is doing the tearing, and it sure as shit ain't Trump or the Republicans.
