Without changing to a proportional representation system, which would require a complete redo of the constitution and government and has its own MAJOR drawbacks, the only real option I see would be instant runoff voting or even possibly more jungle primaries (though I would want to see more testing of those in more states before considering it nationally).
Instant runoff voting would be perfect in my opinion because it lets you choose your favorite candidate without risking handing the win to the other ideology, like you see in some multi party nations. It is still giving victory to the candidate with the most broad support base, but it allows for more flexibility and choice for voters.
