WASHINGTON (AP) — ‘‘2016: Obama’s America,’’ a new conservative film exploring the roots of President Barack Obama’s political views, took in $6.2 million to make it one of the highest-grossing movies of last weekend. The film, written and narrated by conservative scholar Dinesh D'Souza, argues that Obama was heavily influenced by what D'Souza calls the ‘‘anti-colonial’’ beliefs of his father, Barack Obama Sr., a Kenyan academic who was largely absent from the president’s life.
