Charlotte, NC (CNN) - It's show time for Democrats as their national convention gets under way in North Carolina. Their goal is to get President Obama re-elected, while Republicans argue he's had his chance.

President Obama went to Virginia for one final stump speech before Charlotte.

"This is our last stop on the way to the convention," said Obama.

He goes to the Democratic National Convention with his own spin on what Republicans did last week at their convention in Tampa, Florida.

"They spent a lot of time talking about me, didn't spend time talking about you," said Obama.

And Democrats think that gives them a potential break in a tight race.

"Over the course of the week, you'll hear a very different tone than the one you heard last week in Tampa, which was really essentially one nonstop series of attacks on President Obama," said Rep. Debbie Wasserman Schultz (D) Florida.

But Republicans aren't willing to give up the narrative this week, while Mitt Romney prepares in private for upcoming debates, his running mate Paul Ryan is making the media rounds arguing that President Obama's time of blaming the Bush Administration for economic troubles his administration inherited has expired.

"We will not blame others for four years. We will take responsibility and fix this country's problems," said Ryan.

Democrats will retake the spotlight Tuesday night, and one speaker is First Lady Michelle Obama.

"I'm going to be at home watching with our girls, try not to let them see their daddy cry because when Michelle starts talking, I start getting all misty," said Obama.

Unlike four years ago, President Obama will be watching from the White House, and hoping this convention helps him stay there one more term.

Coming up at the Democratic National Convention Tuesday night San Antonio Mayor Julian Castro will be the first Latino to give the keynote address at a Democratic convention.

Former President Bill Clinton headlines Wednesday night, and President Obama makes his speech Thursday.
