Snip -
In the Bloomberg survey, a large share of the respondents voiced concerns with Biden’s age and a significant percentage said Trump was dangerous, and suggested the number of “double haters”, as pollsters call voters who approve of neither candidate, is significant.
Those findings were broadly repeated in Saturday’s Times poll. Biden’s approval rating came in at 38%, with Trump faring better with a 44% favorable rating.
Nineteen per cent of voters said they disapproved of both men, but among them Biden is slightly less hated, with a spread of 7% between Biden (38%) and Trump (45%). That spread, according to the Times, is significant: the candidate less disliked by “double haters” has won the last two presidential elections.
The phrasing is important "the last two elections" are just Trump/Biden and Trump/Hilary.
This means it wasn't true before that. Extremely weak pattern to pin their hopes on.
