Presidential contenders Vice President Kamala Harris and former President Donald Trump are using the week before their debate to sharpen their economic messages about who could do more for the middle class. Harris will use a campaign stop in New Hampshire on Wednesday to propose expanded tax incentives for small businesses. Trump, meanwhile, is betting that Americans crave trillions of dollars in tax cuts — and that growth will be so fantastic that it's not worth worrying about budget deficits. The candidates will debate next week. By the end of the end of the month, early voting will be underway in at least four states.
