From KELOland news, it appears that Jamie Smith is conceding his loss, and is not going to challenge the new Mayor, Christine Erickson’s win in the runoff:
Sioux Falls candidate for mayor Jamie Smith made an announcement Tuesday he’s conceding from the Sioux Falls Mayoral race.
“I’m here today to announce that I will not challenge the results in court and I will concede the race for Sioux Falls Mayor,” Smith said.

Class act Jamie. No suprise there
If he would have won, he wouldn’t have said a word about election integrity.
Nice little dose of sanity this morning.
