You may think it's funny, but if someone is willing to put an ad in a newspaper for people with balance issues, than clearly balance issues affect a measureable portion of those who vote.
It is pretty much a given that older people are more likely to have balance issues than younger people (not counting drunken college aged kids too stupid to know they've had enough). While the younger crowd will actually seek out losing their balance while skateboarding, doing bicycle jumps, or just driving around drunk, older people are more cautious and will avoid places in which their balance issue could result in an unfortunate fall.

It was this kind of voter strip mining of the democratic party that in most cases adversely affected Hillary Clinton and greatly benefited Barack Obama.
