The same way you fight any sort of problem like this. Become the squeaky wheel in your electorate. Highlight clearly the problems that both sides are bringing in together and build a momentum such that the sitting member knows he won't get in and neither will his opposition party person, if they continue to support such notions. If it means a loss for the major parties by having, say, an independent taking over, then both sides will start to listen. However, that kind of activism is very hard work and you have to be prepared for the rest of your electorate to be blaise about the subject matter.
