why did Donald Trump get elected????

Because people voted for him and it was the 'right' thing to do ...and he was NOT lying, cheating, law-breaking, Never-Acheived-ANYthing- Horrible-Hillary !!!!    People want to maintain a sovereign nation, enforce all of our fair immigration LAWS, repeal the ACA (ObamaCare), protect the second amendment , get our economy growing again, reduce unemployment , give opportunities to everyone to work/achieve/be self-responsible  and  live the American dream instead of living off of the largesse  etc etc....            WoooooooHoooo!
