Oops. Obama may have just made a big mistake.

Last week, Vice Presidential Republican Candidate Sarah Palin made this now-famous comment in an exchange with one of McCain's aides, after being warned about the vicious assault she'd be facing once her candidacy was announced:

Palin: “Thanks for the warning. By the way, do you know what they say the difference is between a hockey mom and a Pit Bull?”

McCain aide: “No, Governor.”

Palin: “A hockey mom wears lipstick.”

Comments like that, and the attitude to back it up, have given her approval ratings above 50% in some polls.

With this comment still fresh in people's minds,

Senator Obama made the following comments today, in reference to the McCain/Palin campaign:

“You can put lipstick on a pig, but it’s still a pig,” Obama said. “You can wrap an old fish in a piece of paper called ‘change,’ it’s still going to stink.”

The

reactions have already been strong and swift.

If we take Obama, and add his comment about lipstick on a pig, and add this in as a Palin reference, does that equal a win for McCain? I don't know whether that's true, but I do know that there's only one way to replace the letters below with numbers so that the equation is true. Can you solve it?

Click here to see the rules for this puzzle.The object of this puzzle is to replace each letter with a number so that the equation is true.

The rules are as follows:

• Each letter represents only one digit, 0-9, throughout the problem.

• Different letters represent different digits, and no two letters represent the same digit.

• Any letter that represents the leftmost digit in a number never represents 0.

• When solved, the equation must be true.

• There is only one possible solution.

To start solving the problem, click on any box, and change that box's letter to a number, and then hit the tab key. If that letter appears more than once, the other instances of that same letter will also be changed to that same number. You won't be alerted if you enter the same digit for two different letters, so be careful!

The Hint button will tell you one digit, and which letter represents that digit. The Restore button will set each text box back to its original letter. The Check button will let you know whether your solution is correct.
