The 2024 presidential contest has shifted in the past week, and with 99 days before Election Day, a new race is taking shape featuring Vice President Kamala Harris and former President Donald Trump. 

With President Joe Biden dropping out of the election race, Harris stepped in for him on July 21, raising $200 million in seven days while creating excitement among voters and Democrats that some party members tell the Associated Press is reminiscent of Barack Obama’s historic candidacy nearly 20 years ago.

Harris hasn’t selected a running mate so far, and Trump is uncertain about the prospect of the next presidential debate scheduled for Sept. 10 and hosted by ABC, arguing that it was part of a deal arranged with Biden. 

Harris said last week that she’s ready to debate Trump and accused him of "backpedaling" from a previous agreement for the Sept. 10 debate.

FOX News has invited both candidates to participate in a Sept. 17 debate in Pennsylvania, moderated by FOX News hosts Bret Baier and Martha MacCallum. 

The vice president did not respond to a question from the AP about having Fox News host a debate.

The Associated Press reports that some Republicans are worried that Trump winning the November election is no guarantee as some GOP members are questioning the Republican presidential frontrunner's vice presidential pick, JD Vance.

What are early polls showing?

Recent polls suggest that the events from the last two weeks potentially temporarily reduced voters' frustrations with the rematch between Biden and Trump. 

According to the AP, polls from CNN, the New York Times, and Siena College show that at least slightly fewer voters now hold an unfavorable view of Trump and Harris. This is driven by the fact that both polls show fewer have an unfavorable opinion of Harris than said the same of Biden. However, both polls also suggest a slight increase in the percentage saying they have a favorable view of Trump.
