It's Official for 2016, Obama & Castro Talk, Murder in South Carolina

The 2016 presidential candidates are becoming official. Hillary Clinton and Marco Rubio plan to announce over the weekend. Rand Paul (pictured) is in. How's it going so far? Rich Lowry says Rand Paul had a failed roll-out. Josh Barro says you don't want someone who is making up policy on the fly. Margie Omero says Hillary Clinton's planned video announcement is all she needs. Is Marco Rubio the one with the skills? President Obama and Cuban President Raul Castro talk on the phone -- the second such chat between the two countries in 50 years. Margie Omero said a new poll of Cubans show 97% in favor of normalizing relations between the US and Cuba. Bob Scheer calls the latest moves, "the end game of a half century of war footing." Will the video of Walter Scott being shot from behind by a police officer change public perception of police brutality? Why isn't the topic coming up on the campaign trail?
