I don't believe in none of the shit that's going on in the world."[276] He went on to say that voting was useless: "When I say the president can't even control the world, then you definitely know there's something else out there pushing the buttons. They could do whatever they want to do, we['re] all puppets."[277] Several days before the 2012 presidential election, he reversed his previous claim that he was not going to vote and said that he was voting for Barack Obama because Mitt Romney did not have a "good heart".[278] Lamar later met Obama in January 2016 in promotion of Obama's My Brother's Keeper Challenge. Speaking about the meeting, Lamar said, "We tend to forget that people who've attained a certain position are human."[279] Before the meeting, Obama said in an interview that his favorite song of 2015 was Lamar's "How Much a Dollar Cost".[280]
