"There's a lot of electricity, everyone's really excited about Bernie,” said David Pfau of the Sanders local campaign.
"When it was confirmed, of course, it's exciting because Sacramento's been waiting for Donald Trump to come,” said Tim Clark, California state director of the Trump campaign.
Both local campaigns are happy to see their candidates make the Sacramento area a priority, and both candidates' supporters usually show up in big numbers -- but campaign staffers on both sides say that’s where the similarities end.
"I’m sure the people going to Bernie’s event are very different from the people going to Trump’s event,” said Pfau.
Whether that statement seems like a political jab or not, most likely neither campaign will have to compete against the other for supporters.
Sanders takes the stage at Hutchinson Field at UC Davis at 8 p.m., while Trump's event begins at 7 p.m. in the Sacramento International Jet Center.
In Davis, Sanders campaign staffers expect the event could draw close to 20,000 people -- about the same attendance at his first Sacramento appearance at Cal Expo.
CHP will handle traffic control at the airport and will try to separate regular airport traffic from Trump traffic as best they can.
"We're going to try to minimize the negative impact toward out regular passengers,” said Mark Haneke, marketing manager with the Sacramento International Airport.
Haneke says airport officials met with local, county and state law enforcement Tuesday afternoon.
Trump events have often led to violent protests, something Haneke says they're working to avoid, and say at least four law enforcement agencies, including secret service, will be out in heavy numbers to keep the regular airport flow steady.
"That's the whole reason why we're pulling in joint agencies to make sure there's no problem with that kind of thing,” said Haneke. The event will, however, be open to the public, and therefore subject to protests.
