As you see there was a huge gap in favor of Trump with independents enthusiastic 23-9 over Hillary. Also a huge gap in those upset over Hillary's nomination by the Democrats over those upset by Trump's nomination by the Republicans 57-43%. No wonder Trump won the independent vote.
Throw in those independents who viewed Hillary negative or unfavorable 70% which included 57% who viewed Hillary very unfavorable or negative to how negative independents viewed Trump. 57 total unfavorable with 46% very unfavorable. Questions 10 and 11.
Bottom line, Trump wins the independent/non-affiliated vote and thus the White House.
