A rebel Republican bloc aiming to curb far-right extremism in North Idaho made significant gains Tuesday, flipping dozens of local seats, but fell short of the votes needed to change the hard-line GOP leadership in an area with historic ties to the far right.

Ultimately, however, a majority of members of the county GOP committee kept their jobs.
