MADISON, Wis. -- Obama spirit is alive in this swing state capital.

With the sky still dark and the weather cold, supporters already were lining up outside the capital building for a rally that won't start for four more hours.

President Obama is scheduled to speak here at 10:45 a.m. local time (11:45 a.m. in Washington). By 6:30 a.m., Obama fans had started to gather, holding blue placards and chanting "four more years!"

The president kicks off his last day of campaigning here before traveling to Columbus, Ohio, and Des Moines, Iowa, for his final events of the 2012 cycle. Rocker Bruce Springsteen and First Lady Michelle Obama are scheduled to join him.
