Are we being led in America by a power elite who want to control

Cape May Beach - Are we being led in America by a power elite who want to control elections and policies through the polls that are being taken? An example would be that Hillary Clinton would win the election in a landslide. We had the polls that said Jeb Bush would be the Republican candidate. Donald Trump didn't have a chance. The latest is the polls show Obama with an overwhelming popularity. My conclusion is that people were afraid to say they were for Trump because the press said that he was unstable, and to say Obama was a bad president would be racist.
