MIAMI LAKES, Florida (AP) - First lady Michelle Obama is swinging through Florida, campaigning for her husband and encouraging Americans to register to vote.

Obama met Tuesday with grassroots supporters at Barbara Goleman High School in Miami Lakes.

She heads to Orlando later, where she is scheduled to address a crowd in a 1,800-seat theater at the University of Central Florida Arena.

President Barack Obama is facing an extremely tight race this fall against Republican challenger Mitt Romney. Although the president holds a modest lead in the state, Florida is considered one of the top battleground states with 29 electoral college votes up for grabs.

The trip is Michelle Obama's first official, public campaign jaunt through Florida this year.
