What will the parties do as more and more voters go independent?

Independent voters are poised to break the duopoly that has kept a stranglehold on American politics ever since Grant defeated Lee at Appomattox.

Frankly, both Democrats and Republicans should have seen this coming. At last count, a record 43 percent of Americans have declared their independence from a political party, with nearly two-thirds viewing both parties equally negatively. The major parties' respective decisions to nominate historically unpopular candidates for president three cycles in a row hasn’t done them any favors.
