His main challenger was Republican Mitt Romney. But there were several other third-party candidates on the ballot, like Libertarian Gary Johnson and Green Party candidate Jill Stein. President Obama defeated all of them, to win re-election in November 2012.
At this point in 2012, the election has not yet been held, so we do not know if the Republican challenger, Mitt Romney, will defeat the president, or if President Obama will win a second term in office.
Barack Obama won the president election for 2012.
