This bill is unconstitutional - the D’s know it, the R’s know it - everyone knows it. It will be byotch slapped down by the USSC when it is brought before them but that will take months. But that is not the play being made by the Ds.
The Ds want the bill to become law before the 2022 mid-terms. The provisions in the bill (no voter ID, anyone can vote, unverified mail-in voting, etc) is probably their only hope of victory. After the mids, especially if the Ds retain power, having the law slapped down is of no concern. It will have done what it is intended to do - insure a D political victory.
Congress has authority to make rules regarding the election of Representatives and Senators, right in Article I section 4.
Congress has NO AUTHORITY over the appointment of Electors by the State Legislatures. NONE. ZERO. ZIP. ZILCH. NADA.
Every intrusion - spending limits, "debate commissions", etc, etc is plainly and facially unconstitutional.
There is no such thing as a "presidential election" in the Constitution.
