The main question to ask here, of course, is "Flexibility to do what?"
Well, perhaps candidate Obama can give us some clues:
In the full video, then-candidate Obama later stated that he is fully committed to the policy as outlined above, and that he will "keep (his) promises."
But before you go dismissing out of hand the notion that Barack Obama keeps any of his promises, consider this:
Obama promised that health care 'reform' will pass; it did so, even though via the auspices of Nancy Pelosi and Harry Reid, we indeed did not find out what was in the bill until it was passed.
During the campaign, then-candidate Obama also promised that under his policies, the cost of electricity/energy will "necessarily skyrocket."
That too, has become reality.
There are some promises, of course, that Obama chose not to keep; and one could argue never intended to keep. One was that you'd be able to keep your doctor and your health plan under Obamacare; another that the public would never be forced to pay for an abortion under Obamacare; you know, lipstick-on-a-pig type stuff.
But make no mistake. Obama is a dyed in the wool socialist. Any promise he has made that will serve to further his neo-socialist agenda, and in the process compromise America's economic and military security (remember, America is arrogant and needs to be taken down a few notches), you can bet your bottom dollar (that is, if you have any dollars left when he's done with the economy) he will keep.
So, sleep peacefully under Obama's second term, knowing that he fully intends to bring the United States into the community of feckless, neutered, third-world nations.
How's that hopenchange working for you, anyway?
