The situation that Republicans strove to avoid in Alaska has come to pass: Two Dan Sullivans will appear on the general election ballot for US Senate.

One is an incumbent GOP senator, and the other is a political unknown that the party fears will siphon votes from the senator in a key race for the Senate majority.

But how worried should the GOP be?

In short, history suggests this could hurt the party at least somewhat — but likely only in a very close race.

And Alaska’s unusual ranked-choice system should mitigate some of the potential impact.
