In any event, state law allows for candidates to be replaced by local committees if they bail after the primary, so Republicans won't be left in the lurch if this comes to pass. In fact, according to Capitol Fax, "Johnson apparently believes that this is now a safe seat since perennial candidate David Gill won the Democratic primary race, so it’s OK to leave without partisan worry." But if that's the case, though—that he truly thinks this race has gone all the way to Safe Republican with Gill as the Dem nominee—then why didn't Republicans spend any money trying to ratfuck the Dem primary? (Also, it's not 100 percent certain yet that Gill has won, though it looks likely.) That sounds extremely overconfident at best, so I'm not entirely buying this explanation. Indeed, according to The Fix, Republicans are supposedly trying to convince Johnson not to go through with his plans to pull the ripcord.
I guess we'll either find out for sure in a day—or else be greeted by some very hot denials from the Johnson camp. And if Johnson does call it quits, regardless of what he might allegedly think, this is definitely good news for Democrats, since there's no potential alternate GOP candidate who would be stronger than he is.
