U.S. Election 2016 News
If I had to pick a winner in this election-app horse race, it would probably be the clumsily named U.S. Election 2016 News (if you use the Android app) and Election NF 2016 -- U.S. Presidential Elections News (if you use the iOS app). As the name suggests, it's all about election news, presented here in a straightforward, nicely designed scrolling feed. If you don't like the oversize photos and headlines, one tap toggles a list view with thumbnail images and smaller fonts.
That default view is nice, though, because each story in the feed includes quick-access icons for source, sharing, saving (to a favorites page), more coverage and, when available, accompanying videos. In other words, you don't have to tap through to access those extras; they're right below the headline. The app also provides one-tap access to poll data from Politico, complete with search and filtering options. Best of all, you can customize the news feed to block any unwanted party or person, thus getting exactly the election coverage you want. Just be prepared for the occasional pop-up and interstitial ad.
