Tuesday is expected to be a much quieter Primary Day than most, with only two states voting and no clearly competitive races in either one.

If you’re missing your weekly dose of election excitement, it’ll be back next Tuesday, when voters will go to the polls in crucial races in Arizona, Florida and Oklahoma. But in the meantime, here’s what to watch tonight.

In Alaska, an independent governor runs for re-election

Gov. Bill Walker, the only independent currently leading a state, is running for re-election. The Democratic primary is uncontested, with only former Senator Mark Begich running. On the Republican side, the field is crowded, with seven candidates, but State Senator Mike Dunleavy and former Lt. Gov. Mead Treadwell are considered the front-runners.

A poll released in February found that Mr. Walker was the least popular governor seeking re-election this year. A three-way race in November could split the left-leaning vote and allow Republicans to take the governorship.
