Democrat Mary Peltola, who won the red state’s House seat twice, is also running to unseat the incumbent senator

Dan J Sullivan is a retired schoolteacher and US Forest Service employee living in the town of Petersburg in south-eastern Alaska, who is running as a Republican for the US Senate. Dan S Sullivan is a Republican US senator, who has represented Alaska since 2015.

Both candidates will appear on the ballot, one name after the other, when Alaskans vote in primary elections this week – a complicated quirk of the contest that has drawn howls from Republicans.
