From now on, we should treat pollsters like Reagan did Russia..... trust but verify.....
Were it my call I would outright BAN polling by the media during elections except to poll issues. No polling about candidate preference due to the ease in which these polls can be manipulated to influence voter turnout. Ditto exit polls should be banned since they serve no useful purpose at all.
Only the campaigns themselves should be able to poll the population re candidate preference and even then for their own internal uses only.
