On a presidential debate analysis program on KCRW yesterday a guest gave his thoughts on Andrew Yang's sweepstakes pilot and labeled it a ploy. The host then followed by saying:
I think it goes to an interesting thing about Andrew Yang's support, which is that even though he is running for a democratic primary he has a lot of supporters who would identify as libertarians..."
Does "It goes to..." here mean it explains/says an interesting thing about...?
Why is this not in the dictionary and when did this usage enter the American language?
Can I borrow this and use it in my everyday conversation?
