CHICAGO -- On the same day that Democratic presidential candidate Sen. Barack Obama gained even more superdelegates, his wife talked about her priorities if she becomes first lady.

Michelle Obama spoke on Friday in front of 1,700 people -- mostly women -- at Rep. Jan Schakowsky's power lunch, which also featured former CIA agent Valerie Plame.

While Michelle Obama doesn’t often publicly speak about becoming first lady, she did talk about the possibility, Ahern reported.

"If I have the honor of becoming the next first lady, I want to continue these conversations, like the ones I've had with these incredible women across the country," she said.

Sen. Obama is now three superdelgates ahead of his rival, Sen. Hillary Rodham Clinton, and he has shifted his focus to November's general election, NBC5's Mary Ann Ahern reported. The next primary in West Virginia, and so far, Obama has not scheduled any campaign appearances in that state, and is looking ahead to Oregon on May 20 to claim he has a majority of delegates.

As more superdelgates headed Obama's way, there were more calls from those in the Democratic Party for Obama and Clinton to join forces in what some call a dream ticket, Ahern reported. Others, however, said they were not so sure.

"Potentially, it could be," Schakowsky said. "I don't know how Sen. Clinton feels about that, and I don't know how Barack Obama does, either."

Just this past weekend, before the Indiana and North Carolina primaries, Obama's daughters rejoined the campaign trail, having not really been seen publicly since Iowa.

"At one point, someone asked Malia, our older daughter, what she enjoyed most about the weekend," Obama told the crowd. "She said, 'Being with my dad.' It nearly broke my heart."

Plame told reporters that she and Michelle Obama have much in common.

"We both have small children, we have both been very private people thrust into a public role," she said.
