[Cletus.D.Yokel]

Then there is this:
Amendment XX Section 3

“...the \\Congress may\\ by law provide for the case wherein neither the President elect nor the Vice-President shall have qualified, //declare who shall then act as President//...

[Publius]

So far Congress has not passed a law that would codify Section 3 of the 20th Amendment into law. It’s uncharted territory, and that makes everybody nervous.
