The purpose of the secret ballot is to make it impractical for people to sell their vote.
Mail-in ballots defeat the purpose of ballot secrecy.
Mail-in ballots should only be allowed in cases where a person could not otherwise vote.
I believe ballot secrecy is required by international treaty.
“Article 25
Every citizen shall have the right and the opportunity, without any of the distinctions mentioned in article 2 and without unreasonable restrictions:
(a) To take part in the conduct of public affairs, directly or through freely chosen representatives;
(b) To vote and to be elected at genuine periodic elections which shall be by universal and equal suffrage and shall be held by secret ballot, guaranteeing the free expression of the will of the electors;”
“Every citizen shall have the right and the opportunity...To take part in the conduct of public affairs, directly or through freely chosen representatives”
Lawfare violates international law.
