Rasmussen poll of Trump approval rating today is heavily contradicted. (Inquisitr, 4/16/2017)
CNN notes that Rasmussen also will not disclose how they determine who they call. Most pollsters use a method called random digit dialing, where homes of voters are called randomly, while other pollsters will conduct their polls from a privately maintained voter file. It is unclear which of these methods Rasmussen uses, and Rasmussen will not disclose their methodology.
The Rasmussen poll of Trump’s approval also was not detailed in all aspects of his job, compared to other polls. Rasmussen only reported on job approval and disapproval, whereas other polls went deeper into issues related to the presidency, international affairs, Congress, and foreign policy.
