People are always disgusted with both parties. They were disgusted with Obama in 2012 but that didn't change anything. Based on the polling I have seen there is nothing to suggest that 2016 will be any different than 2012.
I absolutely agree with that. In just about every election that I recall a significant number of people say that they are disgusted with both candidates (and both parties). But eventually they decide and vote for one of them.
