Election challenges are (mostly) resolved but some are still ongoing

I do have one question (though I believe I already know the answer).

First, the challenges:

From the Arizona Secretary of State (AZSOS) (emphasis added by me) -

The "biggest" name to withdraw from a race after the candidate's nominating petitions were challenged was Eric Descheenie, former state legislator, who withdrew from the CD2 Democratic primary.

That sets up a general election contest of Jonathan Nez (now unopposed in the Democratic primary) and incumbent Eli Crane (unopposed in the Republican primary).

On a totally unrelated note, Arizona's "Sore Loser" law seems to preclude a candidate whose petitions were challenged from jumping races and running as a write-in candidate in another race. 

From ARS 16-312 -

F. Except as provided in section 16-343, subsection E, a candidate may not file pursuant to this section if any of the following applies:

1. For a candidate in the general election, the candidate ran in the immediately preceding primary election and failed to be nominated to the office sought in the current election.

2. For a candidate in the general election, the candidate filed a nomination petition for the immediately preceding primary election for the office sought and failed to provide a sufficient number of valid petition signatures as prescribed by section 16-322.

3. For a candidate in the primary election, the candidate filed a nomination petition for the current primary election for the office sought and failed to provide a sufficient number of valid petition signatures as prescribed by section 16-322, withdrew from the primary election after a challenge was filed or was removed from or otherwise determined by court order to be ineligible for the primary election ballot.

4. For a candidate in the general election, the candidate filed a nomination petition for nomination other than by primary election for the office sought and failed to provide a sufficient number of valid petition signatures as prescribed by section 16-341.

G. A person who files a nomination paper pursuant to this section for the office of president of the United States shall designate in writing to the secretary of state at the time of filing the name of the candidate's vice presidential running mate, the names of presidential electors who will represent that candidate and a statement signed by the vice presidential running mate and designated presidential electors that indicates their consent to be designated.  A nomination paper for each presidential elector designated shall be filed with the candidate's nomination paper. The number of presidential electors shall equal the number of United States senators and representatives in Congress from this state.

My question is this: Does this section of Arizona law apply to candidates for Congress?

I ask because someone was a Green Party candidate in CD1 whose petitions were challenged and withdrew from the race is now running as a write-in candidate in CD3.

From the AZ SOS (again, emphasis added by me)

I'm guessing that the "Sore Loser" law doesn't apply to candidates for federal office, but as I'm not an attorney, I don't really know.
