Top 20 most powerful people in the world for 2015 – See who’s number 1! (With Pictures)

13. Warren Buffett 

Not a year goes by, so long as he is alive and in good health, where Warren Buffett is not among the richest and most powerful people in the world. The successful businessman who went from millionaire to billionaire has also been a supporter of what would be considered liberal political causes in the United States. Among them are gun control, Planned Parenthood and, last but certainly not least, Democratic candidates. While Buffett has had positive things to say about Bernie Sanders per the Daily Mail, he has backed Hillary Clinton heading into the 2016 election season.
