Rassmussen is known for polls that always favor Republicans to the point where legitimate pollsters consider them unreliable — but Fox News and right-wing sources constantly report them as factual despite their variance from every other poll.
So now they’re reporting Biden’s high approval rating. Suddenly, the right wing is claiming the pollster they’ve always loved is “fake news.”
Honestly, I’d be shocked if they had reacted differently. That’s always their response to any news that contradicts their already-held beliefs.
