Can you provide A SHRED of evidence, from the Constitution, that the Congress, or the Vice President when acting as President of the Senate, has to or ever has had to "certify" anything?
Appoinment of a new President is a function of State Legislatures. PERIOD.
NOT of "voters". NOT of Congress. NOT of the Vice President, the Supreme Court, or anything else.
It took the Philadelphia convention a long time to sort this out. They kept Federal authorities out of the process ON PURPOSE.
Only if the States could not agree by appointing a majority in the Electoral College would Congress be involved, by the House electing a President and the Senate a Vice President. This has only happened twice, in 1800 and 1824.
Article I gives Congress the right to make rules for the election of Representatives. Amendment XVII extends that right to the election of Senators.
What Article or Amendment gives Congress the right to regulate the way State Legislatures appoint their Electors?
The Zeroth Amendment, that's what. It doesn't exist. There are no Presidential elections in the Constitution.
The existence of 50 separate State elections in 50 separate States for the purpose of appointing Electors does not create a "Federal Election", and it certainly doesn't create a Federal power where none exists.
In today’s America, we know that “the law” means “what you can get away with”. While I agree with your points completely, having Congress reiterate that the VP has no role in the certification is a good thing. Further, it will clearly juxtapose what might be attempted by the Dems against exactly what they railed against 4 years ago. This alone will diminish “what they can get away with”.
