The runoff vote, also known as the alternate voting system.

To address what Fred suggested, I think the reality is people these days vote less for "who is going to work for my district" and more "who is going to work for my party". So it's not so much a worry if areas will get represented, will ideology get represented?

I guess this system, when paired with the run off system, could allow for moderate candidates to appeal to a whole group. Or it could cause partisan candidates of one party in power to sweep.
