Framing the coming election as a choice between fundamentally different visions, President Obama offered himself to the country Thursday as a fire-tested leader ready to finish the job he started.

"Our problems can be solved," Obama said. "Our challenges can be met."

It was an older, battle-scarred nominee who faced his party in Charlotte, N.C. This message of hope was tempered and longer-view — a good distance if not a full turn from the vision he offered four years ago when he accepted the nomination in a thundering Denver stadium.

There were a lot of preliminaries, but it was Michelle Obama's show Tuesday night at the Democratic National Convention, and she used it masterfully — carrying a rapt crowd along with a narrative of family, hard work, and truth-telling.

Largely wrung of politics, the first lady's speech plotted parallels in her life and that of her husband, President Obama. She pointedly tracked their humble beginnings and strivings in an unspoken but clear contrast to the privileged upbringing of GOP presidential nominee Mitt Romney.

They billed the gathering in a Charlotte, N.C., Holiday Inn conference room Tuesday as the first national meeting of Mormon Democrats.

Don't laugh. Crystal Young-Otterstrom says she figures there are 1 million of them out there, and she's determined to find them.

"It's like a missionary effort," Young-Otterstrom said in a room packed with the curious, the media and a cadre of members of the Church of Jesus Christ of Latter-day Saints making the argument that the Democratic Party best represents their personal and religious values.

It's been a rough four years since Barack Obama accepted his party's nomination during a celebratory Denver convention that launched the freshman Illinois senator to the White House.

Recovery from the worst economy since the Great Depression has been excruciatingly slow. The national unemployment rate has remained stubbornly above 8 percent.

In 2008, Barack Obama became the first Democratic presidential candidate in more than three decades to carry North Carolina.

This week, as President Obama heads back to North Carolina to accept his party's nomination, polls show that he may be hard-pressed to repeat his Tar Heel State success of four years ago.

But in the state lies an opportunity for Obama, political analyst Charlie Cook said Monday during a poll briefing in Charlotte, where the Democratic National Convention opens Tuesday.

It's been the political world's obsession for weeks leading into the Republican National Convention in Tampa.

Would nominee Mitt Romney manage what would be miraculous for any candidate, and in a handful of days and one big speech wash away the problems of a modern candidacy?

Turns out Romney's moment Thursday night was a fine one, if not a great one.

His speech continued the campaign's concerted effort to reach out to skeptical female voters, reminding the audience that his strong mother ran for Senate.
