If you want to subscribe to honest reporting on national issues in the United States, there are many reputable and mostly neutral sources like AP, Reuters, BBC out there.

Nola.com (New Orleans)
New York Times
The Advocate (Baton Rouge)
Buzzfeed (Yes, their political reporting is top notch)
Bob Mann Blog
Talking Points Memo
