This is nearer augury than is all that comfortable, but as usual some pollsters came up with answers closer to the results than others ~ that doesn't mean they didn't jigger their own results to get there!
Never ever assume there are not people out there smart enough to outthink polling techniques.
You don't understand how polling works and why the good pollsters can be right the vast majority of the time. I have taken some statistics courses and the construction of polling samples. Internal polls are used extensively by politicians and the government. Don't underestimate their validity and usefulness.
