Every objection should automatically trigger a federal investigation of the individuals and states objecting.
This is ABSOLUTELY INSANE that basic due diligence on the voter rolls has to become a political fight. ALL of these people have a duty to make sure the voter rolls are legitimate.
ANY obstruction of this process by any person should be responded to with arrests.
Show me where in the Constitution the Federal Government has the right to demand that states cough up voting rolls, and the prescribed penalty should they refuse?
I hope that asking politely is only the first course of action.
