This might happen while either completely ignoring, or just not being fully informed of the full scope of a representatives stance. This happens frequently because people aren't encouraged to fully inform themselves. This isn't always the case, but for one reason or another, while the ability to vote for another might be an option [that would properly represent them], they may not know that. Naw'meen? It might not be enough to have a massive seat [like 25%], but it's still enough.
That now is a matter of both the campaigns and the media. I don't know if this happens in the US, but here our public service channel is obliged to air all parties' campaign video, which in turn are obliged to show all their ideologies and propositions for government. That's like 1 hour on prime time every day of campaign time that is divided wisely between 20 parties so everyone has enough time to say their piece. Also, coverage of the campaigns themselves is done without bias in the public service channel, although private channels tend to only focus on the 5 main parties.
That's pretty much it, the parties have to make sure their point gets across with decent campaigns and that the media represents them fairly. Of course, considering Fox News exists, I know that's a very steep mountain to climb.
