It is a serious mistake to say that Ouattara is "the good guy" and Gbagbo is "the bad guy"
Quattara is a Muslim and Gbagbo is a Roman Catholic and was educated (PhD) in France.
Both are smart people, but many nationalistic folks don't want the country to move toward an Islamic majority which will mean Sharia law and loss of liberty.
Gbagdo is (was?) a Marxist and has nationalized much of the business base in the country, hence the opposition from foreign investors. Gbagdo does seem to have the support of the military.
Quattara has said that seizing privately-owned businesses was wrong and that they will, under his ruel, be returned to private ownership, a move that sounds good to many people in developed countries.
The long period of peace and the status as a favorite tourist destination will be lost if violence threatens foreign visitors.
