Exactly. If one looks at the never will vote for, Quinnipiac had that question about a week or so ago. 58% said never to Trump, 55% never to Clinton. If those figures are right, Trump tops out at 42% and Clinton at 45%.
Here is something very interesting along the lines you stated: One in Four Americans Dislike Both Presidential Candidates
One in Four Americans Dislike Both Presidential Candidates
Scroll down to the second graph. 54% of all independents dislike both Trump and Clinton. 24% of all Republicans dislike both Trump and Clinton, 20% of Democrats dislike both Trump and Clinton. Now that is a lot of dislikes. Especially within one's own political party.
But I am sure you are correct. More people will vote for Clinton because they detest Trump than actually support Clinton. The same with those voting for Trump, more will vote for him because they hate Clinton than actually support Trump.
This election sucks to put it mildly.
