Warnock Turns to Obama, and Walker to Lindsey Graham, in Georgia Senate Race

Democrats in midterm races in Pennsylvania, Nevada and other battleground states have sought out Mr. Obama to provide that inspiration and to deliver the closing message to their supporters. In Georgia, the former president had a simple instruction for the Democratic voters who had not yet cast ballots during the state’s early voting period: to head to the polls and expand Democrats’ majority in the Senate.

Hundreds of people filled the sprawling central Atlanta venue, Pullman Yards, that was once used to repair damaged railway cars. Many in the audience — mostly Black, with white, Latino and Asian American attendees — raised signs emblazoned with Mr. Warnock’s face and his campaign’s bright yellow “W” logo. Chants of “One more time” and “Sí se puede” — Spanish for “Yes we can” — often broke out.

The Walker campaign had its own national Republican surrogates visiting Georgia on Thursday.

Mr. Walker held a rally in Woodstock, Ga., more than an hour’s drive from the Atlanta event with Mr. Obama, drawing Senator Lindsey Graham of South Carolina, one of Mr. Walker’s most vocal Republican supporters. Senator Rick Scott of Florida, the head of Senate Republicans’ campaign arm, plans to rally with Mr. Walker in south Georgia on Friday.

In an email Thursday morning, the Walker campaign used the former president’s visit as a fund-raising vehicle. “Last time President Obama was in Georgia, he rallied 7,000 voters and got wall-to-wall TV coverage for Raphael Warnock in the final days of the general election,” the email to Walker supporters reads. “Now he’s looking to have a bigger impact in the runoff.”

Ms. Parsa, the woman who first made the accusations in The Daily Beast on Thursday, described volatile and at times frightening behavior from Mr. Walker apart from the 2005 episode in an interview with The New York Times.

Ms. Parsa, 61, who lives in Dallas and runs a residential and commercial design firm, said she had first met Mr. Walker after a waiter passed him her business card while they were both eating at a pancake restaurant in 2004. She said Mr. Walker’s dissociative identity disorder — which he has discussed openly, including in a 2008 memoir, and claims to have recovered from — led him to adopt what appeared to be different personalities, sometimes during the course of a single conversation.
