Removes provisions for acceptance of mail-in ballots received after election day; increases penalties for violation of ballot messenger and bearer limits and candidate prohibition.

S 1738 eliminates the current allowance for counting mail-in ballots received up to 144 hours after polls close (if postmarked by election day) or within 48 hours of closing (via USPS delivery). It directly affects voters who submit ballots after election day and individuals delivering ballots. The bill increases penalties for violating messenger/bearer rules - such as delivering ballots for more than three voters or candidates acting as messengers - to a second-degree crime, raising the severity from a third-degree offense. It also explicitly prohibits candidates from serving as ballot messengers or bearers. These changes tighten election security by removing post-election ballot acceptance windows and strengthening enforcement of messenger regulations.
