Via Mother Jones, Public Policy Polling (PPP) did a survey [pdf] of 1,072 likely voters in Ohio September 7th through the 9th, 2012. The margin of error is 3%.

Some evil genius came up with a question for the poll. The crosstabulations are very interesting.

Q15 Who do you think deserves more credit for the killing of Osama bin Laden: Barack Obama or Mitt Romney?

Base [all]

Barack Obama – 63%

Mitt Romney – 6%

Not sure – 31%

Democrat

Barack Obama – 86%

Mitt Romney – 1%

Not sure – 13%

Republican

Barack Obama – 38%

Mitt Romney – 15%

Not sure – 47%

Independent/Other

Barack Obama – 64%

Mitt Romney – 1%

Not sure – 36%

[emphasis added]

That’s interesting. It’s curious that it’s not 27%.
