Maria Gavrilovic of CBS News offers 'Obama Addresses N.C. Voter Who Called Him "Socialist"' (link) in which she allows Barack Obama to mislead and confuses what someone says with what they actually believe:

[At a campaign stop in Fayetteville, North Carolina, someone] asked the Democratic nominee about the North American Union, which he opposes.

"I know some people have been hearing rumors about it. But as far as I can tell that's just not something that's happening. We would never give up our sovereignty in that way. Any other questions?" Obama asked [her]...

The NAU is like immigration, in that candidates frequently use misleading language in an attempt to deceive. If Gavrilovic were a real reporter and not just a BHO transcriptionist, she would have asked him about his March statements in Lancaster PA where he more or less confirmed the NAFTA Superhighway, something that's tied to the NAU. He also faked being ignorant of the "Union" part of the NAU term, and he lied about the CFR. And, she'd point out that Barack Obama supports Bush's Security and Prosperity Partnership, something that some consider a precursor to the NAU. Not only that, but he spoke in code when coming out for the SPP.

The article also provides an example of how BHO has been able to get to where he is: because no one has asked him a good, "prosecutorial-style" question. Simply asking someone whether they support the NAU will always result in statements like those made by BHO above. Better questions need to be asked. Also, the person who asked him about the NAU also shouted "socialist, socialist, socialist – get out of here!" to him, something that only makes him look better to many as the MSM comes to his rescue. Note: per this, BHO's full remarks about the NAU were:

"Well, you know, I am opposed to it if it were happening. But it doesn't seem to be actually be happening. The truth of the matter is there is no plans. I've talked to a lot of people, including folks down in Texas. There's no plan to create a common government between Mexico, U.S. and Canada. That's just not... that's just not happening. I know some people have been hearing rumors about it. But as far as I can tell, that's just not something that's happening. We would never give up our sovereignty in that way. Any other questions?"

There may not be formal "plans", however, many powerful people have made proposals, including the CFR. See also Jim Hoagland/Washington Post: Obama should create North American Union.
