On Bill Maher show of April 21, 2017, he read a Pew poll comparing Republican and Democrats. He claims it shows that after the election, most Republicans think we are doing much better economically, when the data shows a slight continuing uptick. On bombing Syria, when Obama wanted to bomb Syria and that only 22% of Republicans approved, but a new Pew poll supposedly shows 88% of Republicans approved of Trump’s bombing of Syria. Democrats held the same 32-37% approval for the bombing, for Trump and Obama. They also did survey on our income tax system. Republicans went from 39% thinking it is fair to 56% thinking it is fair.
This poll would seem to show that Republicans change their opinion of the same data based upon who is in office whereas Democrats maintain their opinions more rationally.
Is this just bias in the system or are these findings legitimate? Were the polls conducted in unfair ways to get the data to show the results desired by an agenda? Are Pew polls considered to be fair and if so, are they being misrepresented to put forth a political agenda?
