Barron's: How the biggest UK bookmaker sees the election
As always, you've totally garbled what you imagine you read, memoryless moron.
As a phone number to be polled, there is no difference between an iPhone or any other smartphone & a cell phone from the '90s. All the same polling problems apply.
Pollsters know how to sample cell phone users, some surveys better than others. The very best methodology belongs to Rasmussen, which is one reason why it has enjoyed such success.
So STFU about iPhones, ignoramus, unless you can make a coherent argument about them based upon facts. You apparently have forgotten that everyone else but you on this board has used cell phones for decades & most probably now have iPhones or an equivalent smartphone, so your idiotic garbage is laughable to us.
