 President Biden and former President Trump are getting ready to face off in tonight's presidential debate. Biden and Trump will be on stage at the CNN studios for the first of two currently planned major debates ahead of this November's election. The 90-minute event will begin at 9 Eastern tonight. A new poll says Donald Trump has taken the lead over President Biden. A Quinnipiac poll says 73% of voters will likely watch the debate, and 16% say each candidate's performance in that debate could lead them to changing their vote.
