States via their Senators must certify their electors and candidates are Constitutionally able to serve and meet all legal requirements:
What on Earth are you talking about?
Article II, clause 2: "Each State shall appoint, in such Manner as the Legislature thereof may direct, a Number of Electors, equal to the whole Number of Senators and Representatives to which the State may be entitled in the Congress: but no Senator or Representative, or Person holding an Office of Trust or Profit under the United States, shall be appointed an Elector"
The US Federal government has NO ROLE WHATSOEVER in the appointment of Electors by the State Legislatures. NONE.
