(UPDATED, 9:44 a.m., with details on Leroy’s filing.)

With U.S. Rep. Raul Labrador abandoning his seat in Congress for a run for governor, who will run for Congress?

We started getting answers Thursday morning.

Former Attorney General and Lt. Gov. David Leroy filed his paperwork for a 1st Congressional District run. (Details from Kimberlee Kruesi of the Associated Press.)

Leroy’s run is not a surprise. In an appearance on “Idaho Reports” earlier this year, Leroy said he would run for Congress if Labrador did not stay put.

Leroy, a Boise attorney, will almost certainly have company in the May 2018 GOP primary.

Former state superintendent Tom Luna issued a statement Wednesday saying he is “strongly considering” a run for Congress.

Here’s the full statement from Luna:

Luna, of Nampa, was elected as state superintendent in 2006 and re-elected in 2010. But he has not appeared on a ballot after November 2012, when Idaho voters overwhelming rejected his three education overhaul laws. Luna did not seek re-election in 2014.

If recent history is any indication, the 1st Congressional District race should be crowded.

In 2006, then-U.S. Rep. Butch Otter decided to give up his seat for Congress to run for governor; state Rep. Bill Sali won a six-person GOP primary and ultimately was elected to Congress. In 2000, Otter won an open, eight-person GOP primary before he was elected to Congress.
