Presidential campaign internal polls are expensive and are done by the best and most experienced pollsters, using top notch staff, with the most reliable methods and large sample sizes. Above all, such polls are meant to be accurate.

Yep, it's mainly the money spent - they're all human calls, and that costs money - only reason Ras and PPP can spam the universe with polls is they do robocalls.>br>

At election time, polling must compete with what is now an extraordinary level of campaign calls that tests the patience of anyone with a landline. A couple of weeks ago, my brother inadvertently answered what proved to be a computerized poll call. He answered the opinion and partisanship parts correctly — solid Romney Republican — but then input the demographics as being that he was a single Black female of Haitian descent with children.
