Thousands of ineligible voters, including dead people, are listed on New Mexico’s voter rolls and are eligible to receive mail-in ballots.

In a court brief filed Wednesday, the Public Interest Legal Foundation outlined several issues with New Mexico’s voter rolls at the same time the state’s Supreme Court is wrestling with whether or not to implement a mail-in-only primary process amid coronavirus fears, Breitbart News reported.

If approved, a mail-in voting system in New Mexico would potentially send ballots to the addresses of 1,681 dead people, 87% of which died in 2018 or before. Some died in the 1980s and are still listed on voter rolls.

An additional 1,519 New Mexico voters are listed as over 100 years old, and 64 of those are 120 years old. Another 3,168 voters are flagged due to concerns they are duplicates, and 200 voters are listed at commercial addresses.

“This is not a theoretical threat: An automatic all-mail election will send thousands of ballots to identified dead, duplicate, outdated, and other problematic addresses,” J. Christian Adams, PILF’s president, said in a statement.

“We know from our data that New Mexico’s voter roll is not maintained to the standard needed for an automatic, all-mail election,” he added. “There are concrete solutions, but rushing headlong to vote-by-mail is not one of them.”

States across the country have been weighing whether or not to hold primary elections during the coronavirus outbreak.

Wisconsin’s governor tried to postpone Tuesday’s state primary via executive order and extend absentee voting but was ultimately blocked by both the Wisconsin and U.S. Supreme Courts.

“Republicans should fight very hard when it comes to statewide mail-in voting," President Trump said Wednesday . “Democrats are clamoring for it. Tremendous potential for voter fraud, and for whatever reason, doesn’t work out well for Republicans.”
