House Democrats are hoping Vice President Kamala Harris pummels former President Donald Trump in the pair’s first and maybe only presidential debate Tuesday night, arguing that the vice president needs to draw a “stark contrast” between her and Trump’s lack of “substance.”

The debate, broadcast by ABC News, will give Harris and Trump the opportunity to discuss their policy stances before the Nov. 5 general election. While Trump is expected to go after Harris both politically and personally, Democrats anticipate Harris will not succumb to the former president’s attacks.
