It is very easy to believe that the supremes would choose to avoid a crisis. The one thought that comes to mind though is what did the oath of office mean to Justice Roberts when he was sworn in. Is he a man who could take that oath then stand and swear in a president that was potentially unconstitutional? I know I couldn't do it. Can he? That is what we the people don't know.
the Supreme Court ruled in the 2000 election, I believe they will stand by the constitution.
