Barrack Obama

Barack Hussein Obama II is an American politician who served as the 44th president of the United States from 2009 to 2017. Previously, before becoming the President of the United States, he was a United States senator from Illinois from 2005 to 2008. Obama was elected as the first African-American president of the United States on November 4, 2008, beating his opponent John McCain (who had 173 electoral votes) by 192+ electoral votes. His first term (2009-2013) began on January 20, 2009, succeeding his predecessor, George W. Bush (2001-2009). The economy noticeably boosted from the 2008 economy fall and as a result, General Motors was reorganized. 
Obama lent his voice to the Walt Disney World attraction, the Hall of Presidents, for the animatronic version of Obama.
During his presidency, Obama was depicted on television by parody versions of him, usually on sketch comedy shows, like Jordan Peele playing Obama in the Comedy Central sketch comedy series Key and Peele, and comedian Fred Armisen playing Obama in the NBC sketch comedy series Saturday Night Live. 
Obama was praised by lots of American people during his presidency due to being the first black president, and thanks to that, he defeated Republican opponent Mitt Romney in the 2012 election, with Obama being sworn in for his second term on January 20, 2013, in the Blue Room of the White House. 
Obama's second term was mostly the same as his first, but with a few changes in members of the Cabinet and the economic performance. He was succeeded by former real estate businessman Donald Trump on January 20, 2017, due to the two-term limit in the Constitution of the United States.
Obama has since become the subject of many Internet memes after his presidency ended, such as Obunga (which depicts a photoshopped version of Obama's portrait from his first term turned into a creature from the manga Terra Formars), and the Obamium/Obama Pyramid (which depicts a 3D model of a triangle, but textured with Obama's portrait from his first term).
Nowadays, Obama is part of his own foundation, the Obama Foundation, a non-profit organization that helps build the Barack Obama Presidential Library in Chicago.
