Michelle Obama probably will not be the first person to jump on the Hillary Clinton bandwagon if her husband loses the Democratic presidential nomination.

That's not to say that she wouldn't work for whoever becomes the eventual Democratic nominee, but the wife of presidential candidate Barack Obama indicated that if her husband doesn't win, she'd have to take a closer look at Clinton before coming up with an assist.

"I'd have to think about that. I'd have to think about policies, her approach, her tone," she said in an interview Monday morning on ABC's "Good Morning America."

"You know, everyone in this party is going to work hard for whoever the nominee is. I think that, you know, we're all working for the same thing. And, you know, I think our goal is to make sure that the person in the White House is going to take this country in a different direction. I happen to believe that Barack is the only person who can really do that," she said.

Obama also was cool to questions about any similarities between her and spousal counterpart Bill Clinton, who was roundly criticized last month for injecting race into presidential politics when he went on the attack against Barack Obama, whose mother is white and father is black.

"I've never sat down and had a conversation with him. I couldn't begin to dissect who he is But I know who I am. And, you know, I don't think there are many similarities in terms of how, you know, we approach it (the campaign), you know, how we were raised, how we think about the world. I think, you know, we are very different people," she said.

Obama said she was not angered by a comment Bill Clinton made after the South Carolina primary -- which Obama won -- in which Clinton noted that Jesse Jackson also won in South Carolina when he ran in 1984 and 1988. That remark was also interpreted as racially charged.

"You know, I don't get angry anymore. This is politics and we've been in it," she said. "It's been nasty. There's nothing new about it. There's absolutely nothing that people are saying about Barack now that they haven't said before."

Asked again about Clinton's comment, Obama said she wasn't surprised by it. "Politics is a game. And if you get into it with your eyes closed, then you're silly for being in it."
