Obama cites Colo. theater shooting, Hurricane Sandy

Striking a theme of national unity in his campaign's final days, President Obama late Sunday night lauded the reactions to two recent tragedies: Hurricane Sandy and the Colorado theater shooting in July.

"Unfortunately, the people of this town understand what it means to grieve better than most," Obama told some 20,000 supporters in Aurora, Colo., the city where a gunman killed 12 people at the screening of a Batman film.

"Just as you have begun to heal as a community, we are going to help our friends on the East Coast heal," Obama said. " We are going to walk with them every step of the way.

"No matter how bad a storm is, we come back. No matter how tough times are, we will thrive."

The Aurora speech capped a day-long campaign swing for Obama, one that took him from New Hampshire to Florida to Ohio and then to Colorado.

The president campaigns Monday in Wisconsin, Ohio and Iowa before heading home to Chicago for the night.

Republican challenger Mitt Romney is in Florida, Virginia, Ohio and New Hampshire.
