Taking a look at 538 polling weights.
The Quinnipiac poll in Ohio has Obama up 5. Silver gives this poll a 1.73 weight.
- Suffolk has it tied and Silver gives it a weight of 0.83
- Angus Reid has it tied and Silver gives it a weight of .61
- PPP has it Obama up 1 Silver gives it a weight of .87
- SurveyUSA has Obama up 3 with a weight of 1.11
It seems to me that Quinnipiac is given too much weight and it so happens to give the largest Obama lead.
Pulse Opinion Research 10/8 has Obama up 1 with a weight of 1.00
Pulse Opinion Research 10/15 has Romney up 1 with a weight of 0.34
The newer poll is given less weight.
Here is the bullshit of his system.
- There is a Quinnipiac poll from 8/21 with Obama up 6 Silver has it weighted 0.60.
- Marist poll on 9/11 Obama up 7 Weighted at 1.05
- PPP poll 9/9 Obama up 5 weighted 1.13 which is higher than the PPP poll for this week!
He has polls from May that have weight.
