I am lazy today and am not researching, but Manmouth was one poll that changed it's numbers a week before election day. Prior to that Manmouth had Hillary up by double digits. They used 500 registered voters, worthless in October. They only samples 900 total. Anything less then 1100 to 1500 likely voters is useless at this stage.

I think that you are correct, and most polls do this for the same reason, they get graded on their accuracy compared with the final results. Their future business depend on this comparison. Prior to the week before, they can push their agenda with no consequence. Like most casual observers, I don't go back and take a look at their earlier polls.
