SACRAMENTO, Calif. — Kamala Har­ris told a friend­ly crowd of Hol­ly­wood donors on Thurs­day they’d be sur­prised by how many states she’s vis­it­ing dai­ly, if only virtually.

Ear­li­er in the week, she’d cam­paigned before sup­port­ers in Min­neso­ta, Cal­i­for­nia and Con­necti­cut, and she was greet­ing Mis­souri donors next.

Har­ris hasn’t been on a plane in more than a month. Three weeks after join­ing Joe Biden as the Demo­c­ra­t­ic vice pres­i­den­tial nom­i­nee, the Cal­i­for­nia sen­a­tor is still cam­paign­ing large­ly in front of a com­put­er screen to rel­a­tive­ly small audiences.

That’s about to change. On Mon­day, Har­ris will trav­el to Mil­wau­kee on her first tra­di­tion­al cam­paign trip. Biden’s cam­paign hasn’t yet said what she plans to do in the crit­i­cal swing state. Her trip to Wis­con­sin comes after Biden vis­it­ed Kenosha this past week to meet with the fam­i­ly of Jacob Blake, who was shot by police, and talk to the com­mu­ni­ty about racial jus­tice and protests in the city.

The coro­n­avirus pan­dem­ic has rad­i­cal­ly altered cam­paign­ing for Democ­rats, who, unlike Repub­li­cans, are large­ly avoid­ing in-per­son gath­er­ings and orga­niz­ing digitally.

For Har­ris, that’s so far meant a mix of fundrais­ing and orga­niz­ing events, along with local press inter­views and one speech aimed at Pres­i­dent Don­ald Trump’s han­dling of the coro­n­avirus. Lean­ing into her role as the first Black woman on a major party’s pres­i­den­tial tick­et, Har­ris has spo­ken with Black lead­ers and activists in events that aren’t open to the press, but she did not trav­el with Biden to Kenosha.

“She’s been on the road. She’s out her­self,” Biden said Fri­day. “I talk with her almost every day. I speak with her and we work togeth­er and I have every con­fi­dence in her. There’s noth­ing about not cam­paign­ing togeth­er, it’s about being able to cov­er more territory.”

Har­ris, who has not held a wide-rang­ing news con­fer­ence since join­ing the tick­et, was mak­ing her first solo Sun­day show appear­ance as the nom­i­nee, a taped inter­view with CNN’s “State of the Union.”

Accord­ing to an excerpt released Sat­ur­day, Har­ris would not say direct­ly whether she would get a coro­n­avirus vac­cine if one were ready before Elec­tion Day. She also sug­gest­ed pub­lic health experts will be “muz­zled” from hav­ing the last word about a vaccine’s effectiveness.

“I will say that I would not trust Don­ald Trump and it would have to be a cred­i­ble source of infor­ma­tion that talks about the effi­ca­cy and the reli­a­bil­i­ty of what­ev­er he’s talk­ing about,” she said.

Demo­c­ra­t­ic observers say Har­ris is so far com­ple­ment­ing Biden in a way that’s expect­ed for a run­ning mate. It’s the role of the vice pres­i­den­tial nom­i­nee to boost the pres­i­den­tial candidate’s agen­da, as Har­ris has done, and reach out to con­stituen­cies that may not be as nat­ur­al for the nom­i­nee, said Karen Finney, a Demo­c­ra­t­ic strate­gist who ran com­mu­ni­ca­tions for Sen. Tim Kaine of Vir­ginia, Hillary Clinton’s run­ning mate in 2016.

Vice Pres­i­dent Mike Pence, for exam­ple, was cho­sen in part to help boost Trump’s sup­port among evan­gel­i­cal vot­ers, a key Repub­li­can con­stituen­cy not orig­i­nal­ly seen as nat­ur­al Trump allies. Har­ris, mean­while, coun­ters the 77-year-old Biden as a 55-year-old Black woman.

“They have sim­i­lar val­ues, but she also has had a dif­fer­ent expe­ri­ence,” Finney said.

In pri­vate events over the past two weeks, Har­ris has met with Black lead­ers and activists to thank them for their sup­port and moti­vate them as the cam­paign enters the final stretch. Last Sat­ur­day, Har­ris held one with Black women lead­ers who had urged Biden to choose a Black woman as his run­ning mate and anoth­er with Black men, said Don­na Brazile, a for­mer head of the Demo­c­ra­t­ic Nation­al Com­mit­tee, who was on the first call, where singer Bebe Winans ser­e­nad­ed Har­ris with his song “Born for This.”

“We had a won­der­ful time just show­er­ing her with pow­er­ful ener­gy for the bat­tles ahead,” Brazile said.

Brazile said it will be impor­tant for Har­ris to get out for non-vir­tu­al events “where she can actu­al­ly see the pulse of peo­ple,” but she said the dig­i­tal orga­niz­ing has cre­at­ed strong enthu­si­asm. This week, Brazile joined a video call with stu­dents from his­tor­i­cal­ly black col­leges and uni­ver­si­ties as they spoke about how to boost Har­ris and hold cam­pus vot­er reg­is­tra­tion dri­ves. She’s also been invit­ed by friends to join orga­niz­ing groups of sub­ur­ban women sup­port­ing Har­ris and mar­veled at the Har­ris-spe­cif­ic T‑shirts and oth­er mer­chan­dise peo­ple are cre­at­ing and sell­ing online.

“She did some­thing to make the VP seem like a rock star and peo­ple are just donat­ing,” Brazile said.

The cam­paign declined to release fundrais­ing num­bers for Harris’s events, but sev­er­al orga­niz­ers said on calls that inter­est in giv­ing rose sharply when Har­ris joined the tick­et. That’s despite her own pres­i­den­tial bid end­ing last year before pri­ma­ry vot­ing began as she strug­gled to raise mon­ey. Biden raised a record $365 mil­lion in August.

In video calls fea­tur­ing dozens of donors, Har­ris talks about Biden and their plat­form before tak­ing ques­tions on every­thing from the coro­n­avirus to protest vio­lence and what to do if Trump refus­es to accept the elec­tion results. (“If he’s fool­ish enough to try a stunt like that, he will fail,” she said.)

Atten­dees range from Hol­ly­wood pow­er­hous­es like TV direc­tor Chuck Lorre and actress Kate Hud­son to friends and top Kaine donors.

“It’s been increas­ing­ly clear that the response from con­trib­u­tors went up dra­mat­i­cal­ly when you were named as vice pres­i­den­tial nom­i­nee,” Mer­le Gins­burg, a donor who helped orga­nize a Con­necti­cut-based fundrais­er on Tues­day, told Harris.

Beyond rais­ing cash, she’s joined calls focused on return­ing to school in Min­neso­ta, mobi­liz­ing Black women vot­ers in Detroit and reach­ing out to His­pan­ic vot­ers in Mia­mi. In those events, she often gives remarks at the top and, if she takes ques­tions, takes them from event orga­niz­ers rather than par­tic­i­pants. Min­neso­ta, Michi­gan and Flori­da are key swing states.

Steve Ben­jamin, may­or of Colum­bia, South Car­oli­na, said Fri­day it makes sense that Har­ris has been used main­ly in a fundrais­ing role thus far but that vot­ers want­ed to see her more.

“The impor­tance of on-the-ground expo­sure, peo­ple see­ing you in the com­mu­ni­ty, is so impor­tant,” said Ben­jamin, who ini­tial­ly sup­port­ed Mike Bloomberg’s 2020 Demo­c­ra­t­ic pres­i­den­tial bid before back­ing Biden. He joined Harris’s pri­vate call with Black male lead­ers, dis­cussing issues like racial injus­tice and eco­nom­ic inequal­i­ty. He said he expects there will be oppor­tu­ni­ties for Har­ris to get out in swing states like Wis­con­sin, Penn­syl­va­nia, North Car­oli­na, Flori­da and Georgia.

“It mat­ters right now,” he said. “More and more cit­i­zen engage­ment by Sen. Har­ris is what peo­ple want.”
