Yes, it's a good idea for news organizations to report on Dem and GOP WH 2016 right now. It's important. It's likely a good story.
But so is what's happening in Congress. So is implementation of various laws in the executive branch departments and agencies. So is what's happening in the White House. So is what's happening in the states. And in the courts.
Presidential nominations are absolutely very important, but so are House and Senate elections, both in 2014 and 2016. Including the nomination battles in those contests. Including not just the horse race stories and the implications for partisan balance, but also the fights over policy, and the question of what kind of Members of Congress the winners are going to be. And the same is true for gubernatorial elections and other statewide contests, and for state legislative elections.
So, yeah, by all means, cover presidential nominations right now. But keep in mind that there's a lot more to American government than the president, and a lot more to American elections than presidential elections.
