The answer to the question is Yes.
Consider the complete graph on $n$ vertices with one edge removed. It is easy to see that the 2 vertices adjacent to the sole edge that was removed are the only ones that are not popular. So the share of popular vertices is $\frac{m-2}{m}$$\frac{n-2}{n}$, which converges to 1$1$ as m$n$ grows large.
