McCulloch and his Gers team-mates are now 20 points clear at the top of the Irn-Bru Third Division and could clinch the title this Saturday.
If they beat Stirling Albion at home and second-placed Queen's Park draw or lose to Annan away, they will not be caught – and it will be a sweet moment for the skipper if that happens given what he has been through with his boyhood heroes in the last 12 months.
It will also help to ease the pain of the hugely embarrassing 2-1 defeat Rangers suffered to part-time minnows Annan at Ibrox nine days ago.
Ally McCoist and his stunned players were savaged after the surprise loss to the tiny Galabank club – and their very futures were called into question.
McCulloch admitted: "It was a bitter defeat against Annan, a real sore one for everybody. It was really important that we bounced back at the weekend against Elgin and we did that.
"With the size of the lead we had, complacency can creep in. But I don't think we should use that as an excuse. We should still be kicking on and doing better than we did.
"But it doesn't matter now. The game is gone. What matters is that we keep picking up points and get to where we want to be – which is picking up the title."
McCulloch netted his 24th goal of the season when he slotted home a second-half penalty in the 1-0 victory at Borough Briggs. He felt the win and overall display at a difficult away venue in demanding wet and windy weather conditions proved to their many detractors that they are desperate for Rangers to do well.
He said: "Getting the three points was just what we needed. But I also thought the way we got our three points was very encouraging as well.
"We were solid at the back, which we haven't been for large parts of this season, the midfield played really well, young Robbie Crawford especially, and we created chances.
"All in all, I think we have to be pretty pleased with how we performed. I think it made a statement. It showed we care and want the club to succeed.
"We know what happened against Annan was completely unacceptable. But we all know that as players and as a team, and I think we responded in the right way.
"If we continue to show the sort of attitude and application we did at Elgin then I think we will get to where we want to be and wrap up the league soon – hopefully this weekend."
