A Trump victory, will not be good for Indos and Afros on GNI. His supporters are mainly nativists who are anti-immigrant and racist. His supporters see him as the last white person who can take back America to the dark days when non-whites were discriminated against.
He will not win because even though Hillary has a large negative favorability, Trump does not have the numbers to win the general election, despite the problems she faces with her emails.
I dont think its going to be a close election either...when it comes to voting voters will have to weigh the value of having a crazy prson with dictatorial tendencies against one who might be corrupt but will be more predictable. Besides, Trump had 8 more days to make himself a fool.
The best Republicans will have to hope for is to rebuild the party after Trump. They will do their darnest to stifle a Clinton Presidency and make it so crippled that it will be difficult for her to achieve much. They can do all of this and try to make hers a one term presidency.
