The scheme to confuse Alaska voters with a second “Dan Sullivan” on the Senate ballot now has the full attention of federal law enforcement. On Friday, U.S. Attorney Michael Heyman of the District of Alaska stepped to the Justice Department podium and made a promise to the people of his state.

“Every Alaskan deserves a fair election, and they’re going to get one,” Heyman said. “If you’re an Alaskan voter, cast your ballot for the individual who you intend to support. Federal and state law enforcement are working to make sure your vote counts.” He said federal and state partners, including the Alaska State Troopers, are working closely together to preserve the integrity of the election, and added that as an Alaska voter himself, what he has learned is “deeply troubling.”

The case centers on a little-known Daniel J. Sullivan whose name appears on the ballot alongside Republican Sen. Dan Sullivan. The New York Times has reported that Democratic-aligned operatives recruited the decoy candidate. The White House is not mincing words. “It is a criminal conspiracy to disenfranchise the voters and citizens of Alaska,” Deputy Chief of Staff Stephen Miller said.

President Trump has called it what it is: “It’s called voter fraud. It should not have been allowed to happen.” Gov. Mike Dunleavy has also ordered a state investigation, and federal investigators are moving on the case as Alaskans head to the polls.

The message for Alaska voters is clear: know your candidate, vote for the real Dan Sullivan if he is your choice, and trust that the Trump Justice Department is watching. Election Day is Tuesday, Nov. 3.
