And only a few years ago you could get a visit from the Secret Service for having an anti-Bush poster in your room

Can you imagine what would have happened had someone put a Facebook poll like this up when George Bush was president?

The U.S. Secret Service is investigating an online survey that asked whether people thought President Barack Obama should be assassinated, officials said Monday.

The poll, posted Saturday on Facebook, was taken off the popular social networking site quickly after company officials were alerted to its existence. But, like any threat against the president, Secret Service agents are taking no chances.

"We are aware of it and we will take the appropriate investigative steps," said Darrin Blackford, a Secret Service spokesman. "We take of these things seriously."

The poll asked respondents "Should Obama be killed?" The choices: No, Maybe, Yes, and Yes if he cuts my health care.
