In 2008, Barack Obama won the Presidential election over his Republican rival, Arizona Senator John McCain. In 2012, he won again, defeating his Republican rival, former Massachusetts governor Mitt Romney.
Interestingly, Barack Obama has won every political contest he has ever entered, except for one. He entered politics in 1996, winning a seat in the Illinois State Senate, where he ultimately served three terms. But in 2000, he tried to run for the US congress. By most accounts, he ran a poor campaign, and he lost badly to incumbent Representative Bobby Rush. It was the only campaign Mr. Obama lost, and in 2004, when he ran for congress again, this time he was successful and was elected a US Senator.
Actually, no-one defeated him. President Obama ran for a second term, and he won. He defeated his Republican challenger Mitt Romney, and also defeated the third-party candidates like Gary Johnson and Jill Stein.
There was no election in 2009. Barack Obama became president because of the 2008 election. He defeated his challenger, Republican Senator John McCain, in November 2008. But the president did not take office until January 2009.
