CNN's awful Islamic Center polling question

Here it is [emphasis added]:

As you may know, a group of Muslims in the U.S. plan to build a mosque two blocks from the site in New York City where the World Trade Center used to stand. Do you favor or oppose this plan?

Left out of the question is the fact that a mosque already exists just blocks from where the World Trade Center used to stand, and the fact that the mosque would be part of a $100 million community center that would be open to all New Yorkers and would house a performing arts center, lecture hall, and swimming pool.

CNN.com spells all that out in its article about the poll. But oops, CNN forgot to tell that to people when asking the “mosque” question.
