Singapore US Election
President Obama supporter Mallory Riegger of Tucson, Ariz., an American living in Singapore, celebrates after hearing news on the presidential election results on Wednesday, Nov. 7, 2012, in Singapore. Obama won re-election Tuesday night despite a fierce challenge from Republican Mitt Romney, prevailing in the face of a weak economy and high unemployment that encumbered his first term and crimped the middle class dreams of millions.
