@msolga,
The Rasmussen poll I find on this came out Wednesday and was of 1000 likely voters. The title of the poll was "Voters Question U.S. Protection of Secrets..."
Summarizing Rasmussen- who starts with "Generally Speaking..."
29% think that the government does a good job of protecting secrets.
46% think that the government does a bad job.
25% are not sure.
79% are at least Somewhat Concerned that the WikiLeaks drop will harm U.S. national security. 47% are Very Concerned. 18% are Not Very or Not At All Concerned.
That is all I can find on Rasmussen about his polling on this.
I wonder where the Guardian got its Rasmussen poll.
