Barack Obama's first term was disasterous for the country, and despite most Americans feeling the country is going in the wrong direction, a complicit media did what it could to cover up Obama's indiscretions and hide the truth. Barack Obama and a Democrat controlled congress passed Obamacare in the dead of night on Christmas eve against the will of the people. Barack Obama has also alienated traditional allies like Israel.
Barack Obama and his state department abandonned our Ambassador to Libya by not providing he and his staff witih adequate security despite countless requests. Ultimately on September 11th, 2012 the LIbyan consulate was attacked by a coordinated terrorist group. The Ambassador and three other Americans were killed. The seige lasted 7 hours and was seen in real time by the President in the White House war room, and despite desperate pleas for help, American forces were told to stand down.
Barack Obama's policies has increased poverty and driven up prices for all good especially food and fuel. His 2012 campaign offered nothing for the direciton of the country. I believe a second term would be even more disasterous as he doesn't need to run for reelection.
