Harris and her running mate — whoever that is — will launch into an aggressive, seven-state battleground tour that begins in Philadelphia on Tuesday and winds through Wisconsin, Michigan, North Carolina, Georgia, Arizona and Nevada.
Her early rallies have attracted enthusiastic thousands. Campaign officials say each stop will be loaded with local election officials, religious leaders, union members and more in an effort to show the diversity of her coalition.
Campaign officials are aware that momentum can be fleeting and are working to capitalize on the energy now, while managing expectations by continuing to emphasize that the race with Republican nominee Donald Trump is tight.
