All 105 legislative seats are up for grabs this year.

And Idaho has a wide-open race for a Supreme Court vacancy.

And then there are the races for Idaho’s two seats in Congress, and a U.S. Senate seat.

The election season began with the two-week candidate filing period, which closed at 5 p.m. Friday.

Here’s a look at the lineup:

Federal races

U.S. Senate: Republican Mike Crapo has filed for a fourth six-year term. He has a Democratic opponent, Jerry Sturgill of Boise. Two Constitution Party candidates, Ray Writz of Coeur d’Alene and perennial candidate Pro-Life of Letha, will meet in a rare third-party primary.

1st Congressional District: Republican Raul Labrador will seek a fourth term. He has two GOP primary opponents: Gordon Counsil of Caldwell and Isaac Haugen of Santa Rosa, Calif. Three Democrats have filed: Staniela Nikolova of Moscow; James Piotrowski of Boise and Shizandra Fox of Santa Rosa, Calif.

2nd Congressional District: Republican Mike Simpson will seek a 10th term. He has a Republican primary opponent, Lisa Marie of Boise. Boise Democratic Jennifer Martinez has filed for the seat. Constitution Party candidate Anthony Tomkins of Twin Falls has also filed.

Idaho Supreme Court

The race to succeed retiring Chief Justice Jim Jones has attracted six candidates: Robyn Brody of Rupert; Sergio Gutierrez of Nampa, an Idaho Court of Appeals justice;  Curt McKenzie of Nampa, a Republican state senator who is leaving the Legislature; Wm. Breck Seiniger of Boise, who ran unsuccessfully for Supreme Court in 2014; Christ Troupis of Eagle, an unsuccessful Republican candidate for attorney general in 2014; and Clive Strong, a deputy attorney general specializing in water issues. All six names will appear on the May 17 ballot. Unless a candidate clears the 50 percent threshold, the top two candidates will meet in November.

In the other Supreme Court race, Roger Burdick is running unopposed.
