Trump got the most votes of any Republican candidate in history. It probably would have been lower than 9% if Trump hadn't run.
Is it pertinent to point out that he also garnered the most votes against him than any Republican candidate in history?
The media thought that everyone not voting for him was voting against him. They assumed that once the field narrowed voters would rally around another candidate and defeat Trump. That never happened. If the voters' goal was to beat Trump, they would have done it.
By that logic, Obama had a record number of votes "against" him too, with 19,585,539 (53%) "against" him in a 3 man race, compared to Trump with 17,151,110 (55%) "against" him in a 5 man race.
