That definition? Easily. Please bear in mind that the comment that caught my eye was the suggestion that Steve Forbes is a “globalist,” and that implied he would vote for Hillary Clinton. I doubt that the poster was suggesting that Forbes is in favor of one-world government (your definition).
Okay, fair enough for a start. But the very word “globalism” implies a one world government - or at least a one world autocracy of some kind. That’s why it’s “global.”
