Dan Sullivan endorses Dan Sullivan to beat Dan Sullivan in perplexing Alaska Senate race

A third Dan Sullivan — a former Anchorage mayor — has weighed in on the competitive Senate race, endorsing Sen. Dan S. Sullivan over former teacher Dan J. Sullivan.

A new Dan Sullivan has entered the conversation surrounding the Alaska Senate race, in which incumbent Dan S. Sullivan faces a candidate with the same name.

The Republican former mayor of Anchorage, Dan A. Sullivan, endorsed GOP Sen. Dan S. Sullivan for re-election over retired teacher Dan J. Sullivan and Democratic former Rep. Mary Peltola on Tuesday.

“As the OG Dan Sullivan, I urge Alaskans to vote for Sen. Dan S. Sullivan. He’s been great for Alaska,” the former mayor wrote on Facebook.

Both Dan S. Sullivan and Peltola advanced to the general election in November after the all-party primary last week. The primary is decided by ranked-choice voting, and the top four finishers advance, regardless of political affiliation. NBC News has not yet made a call regarding who the other two candidates will be, but Dan J. Sullivan could be among them.

Alaska’s Senate race is considered one of the most competitive this cycle, when control of the upper chamber hangs in the balance. With primary votes left to count, Peltola so far has 48% of the vote, with Sen. Dan S. Sullivan taking 43%. Dan J. Sullivan — who is running as a Republican — has 2.4%, with other candidates getting considerably fewer votes.
