Does Rasmussen still adjust its results by party identification ?
"Pollster: Rasmussen Research has a pro-GOP bias
"Rasmussen Reports uses research techniques that make its polls favor Republicans, Ipsos Public Affairs research director Mallory Newall said Monday during an appearance on “What America’s Thinking,” Hill.TV’s new show about public opinion research.
Newall singled out Rasmussen's practice of adjusting results by party identification in arguing that the pollster, which has been touted by President Trump and often has shown him with higher approval ratings than in other polls, favors the GOP.
“I think they tend to be more along the partisan angle, leaning toward the Republicans ... the weight that they put toward partisan self-identification,” Newall said, referring to Rasmussen’s long-standing practice of adjusting its results by party identification."
