Just to be clear. A lot of ignorant people read the rightwing tabloids (DM, DE, S etc) but it does not follow that everyone who reads these papers is regarded as ignorant.
I have never suggested that, nor would I. Simple logic. Lots of ignorant people will vote in a certain way, but that does not mean that all others who vote in that way are ignorant.
What is true is that newspaper readership strongly influences voting intention. I predict that some rightwing papers will use the latest appalling terror attack as a reason to vote for the TM party as they will be credited with being "the party of law and order" in spite of the massive cuts to the police while TM was home secretary.
