The president nominates supreme court justices, who have to be confirmed by the Senate. The idea of removing any Justices, without controlling the replacements is asinine.
The next president will replace Scalia and may also replace Ruth Bader Ginsberg, Anthony Kennedy, and Stephen Breyer (all of whom will be 80+ during that term). If a democrat is elected or if Trump does not pick reliable conservative justices, abortion on demand will be the law until 2050.
With pre-born genocide being the law of land our nation will not be permitted to continue by God who does not forgive nations that allow it. The Biblical consequence of invasion and conquest can be delayed with repentance and revoking the permissive laws but the judgment is reprieved.
