CHARLOTTE, N.C. -- "Oh my goodness, I'm still thrilled."

And so were most who attended one of several caucus meetings Wednesday morning to, once again, hear the First Lady speak.

"Michelle is such an asset. I'd like to have a few years of her as president, too," said California delegate Sandy Hester.

Mrs. Obama used the opportunity to challenge supporters.

"This is where the work comes in. We can give good speeches and be all enthusiastic but the bottom line is the work," she said.

She urged them to travel to battleground states, knock on doors, make phone calls and of course, donate.

"If you can afford to write a check, then write a check. If you’ve written a check and you haven’t maxed out, max out,” Obama said.

As the First Lady works hard to build momentum and rally her husband's base, so is her counterpart this election season. The Republican presidential candidate's wife, Ann Romney, held her own "Women for Mitt" rally out in Ohio.

"I promise you, you will have a better future if Mitt is the president," Mrs. Romney said.

"Both Mrs. Romney and Mrs. Obama are crucial to their husbands because from what I can tell, they are indispensable partners in those marriages," said California Representative Xavier Becerra.

The focus in both camps, with the wives helping to lead the charge, is energizing each base to get out the vote.

Washington delegate Germaine Kornegay said, "After this convention, I don't know how we cannot get engaged."

While the First Lady has those at the Democratic National Convention fired up, there's still a lot of work to do to recapture that 2008 magic.

"In 2008, a lot of us were out there, we were really passionate about him being president. But I think now we have no other choice. Romney is the extreme," said Erika Andiola.

Many still wrestling with the euphoric expectations of four years ago and the reality of today.
