I always hate it when I see an incumbent run unopposed. The easy way to fix that, is to run for the office yourself. After all, wouldn't you like to see a candidate who shares your views? Well, who's more of an expert n your views than you are?
It doesn't take much to get on a ballot. There's usually a filing fee, but you can often get this waived by getting enough signatures on a petition. (Here in Tulsa, that's 300 signatures. If you can't get that many going door-to-door in a week, well...)
On your campaign, you can spend as much or as little as you want. A lot of paper candidates are just happy to get their names on the ballot, but you can usually get permission to speak at at places like assisted living centers, and elderly people usually are voters.
Try calling in on a few local radio talk shows. And shoe leather is cheap. Make up a few one-page brochures on your computer, and get them copied or printed up so that you can have something to hand out.
At the very least, you'll force the other guy to spend money and campaign. And who knows? Stranger things have happened.
Onward and upward,
