The Republican candidate to be Pennsylvania's governor, Doug Mastriano, appeared to take unusual measures to avoid questions on Wednesday as the RV that typically shuttles him between campaign events left a stop without the candidate on it after ABC News waited by the vehicle.

When ABC arrived at the small meet-and-greet in Galeton, a town of less than a thousand people near the New York border, the bus, embroidered with the campaign’s logo, was parked in front of a motorcycle shop hosting the event.

But toward the end of Mastriano’s remarks, when ABC went to the bus to meet the candidate as he walked toward it, as he did at the previous stop, the RV had been driven to the back of the building, near a rear door.

As ABC News waited by the bus, a campaign spokesperson named Matt walked out, said Mastriano would not have time for questions and then reentered the building.

A few minutes later, the RV backed away and drove out of sight.

On the other side of the building, an attendee confirmed that Mastriano had left in a car.

If Mastriano was in fact avoiding questions from the press, it would not be the first time he’s done so. But six weeks from Election Day, amid a campaign underfunded and shunned by some national Republican groups, Mastriano appears to forging ahead with a strategy focused on conservative grassroots turn-out in towns like Galeton.

Security and intelligence agencies are boosting their efforts to monitor online threats of political violence -- which some experts say have been exacerbated by election denialism -- as November's midterm races rapidly approach.

"We're seeing these conspiracy theories and other narratives being promoted online by extremist groups and conspiracy theory organizations like QAnon. On the other hand, we're seeing mainstream public figures in government in politics, even in the media, mimic and amplify these fringe narratives, these conspiracy theories. And that's very powerful in the sense that it tells people that these ideas aren't that wacky," John Cohen, a former Department of Homeland Security intelligence official, told ABC News.

As intelligence officials see election conspiracy theories rapidly become part of the cultural mainstream, agencies are spending more time trying to combat the misinformation before it leads to violence.

Chris Rodriguez, the director of the Homeland Security and Emergency Management Agency, which helps track threats and inform law enforcement officials, told ABC News that the danger from right-wing extremists has grown.

"We've really seen an evolution of the threat. We're seeing a lot more threats toward local elected officials, for example, people in communities who actually run elections," Rodriguez said. "We've also seen calls for what is referred to as a quote 'second Civil War,' which is, again, very troubling and very concerning."

Now, Rodriguez's agency is doubling down on the coordination of information-sharing with partners.

"We've been communicating with authorities in Pennsylvania and Ohio and Arizona and Colorado to make sure, again, that we are we're doing the best that we can to keep our election officials, people who are administering elections and the public at large, safe and secure."

California Democratic Gov. Gavin Newsom again criticized his party's midterm campaign strategy in an interview with MSNBC on Tuesday from Austin, Texas, blasting Democrats for what he called ineffective "messaging problem" that has persisted for years.

"We need to be more assertive to wake folks up," Newsom said.

"There's no doubt states are on the front lines of the rights battle. Period. Full stop. And the Supreme Court now has made that crystal clear … We allow these culture wars to take shape. And we consistently are on the back end of them."

The remarks follow a speech he made this weekend at the Texas Tribune Festival, where he said the Democrats are "getting crushed" by their GOP opponents due to their backseat campaign style while Republicans "dominate with illusion."

The one-term blue state governor has said he does not plan on running for the Democratic presidential nomination in 2024 despite increased national media appearances and political ventures, like his reelection campaign's rental of pro-abortion billboards in six states with near-total abortion bans.

On Wednesday, he said Democrats can turn it all around, "if we go on the offense."

"That's why I'm doing the billboards. That's why I'm doing these ads. That's why I'm doing these TV commercials in other states. Take it to them," he said. "People are losing their rights. We can't sit by but you've got to push back. We've got to hold them accountable. And yes, we prepare ourselves for the great reconciliation, and that's to come --- because we can't, for no other reason, we can't live like this."

Nevada, known for its consistently tight political races, is set to play an outsize role in this year's midterm politics given an array of what are expected to be margin-of-error contests for the Senate and more.

The Silver State has tilted narrowly but decisively toward Democrats in most election cycles since 2016 -- most recently handing the party its six Electoral College votes for president, the governor's mansion, both Senate seats and three out of four House districts.

But Republicans are mustering their political might to flip several of those offices in a year that is anticipated to favor the GOP.

Former state Attorney General Adam Laxalt, a Republican, is running to unseat first-term Democratic Sen. Catherine Cortez Masto, while Clark County's Republican Sheriff Joe Lombardo is facing Democratic Gov. Steve Sisolak.

Democratic Reps. Steve Horsford, Susie Lee and Dina Titus are all running to protect their Las Vegas-area House seats, and Democratic attorney Cisco Aguilar is running for secretary of state against Republican Jim Marchant, who has pushed baseless conspiracies about the 2020 presidential race.

Senator Elizabeth Warren, D-Mass., is expected to campaign on Oct. 26 for Wisconsin Gov. Tony Evers, Lt. Gov. Mandela Barnes and state Attorney General Josh Kaul in what is the latest appearance by a prominent Democrat to rally voters weeks before the high-stakes midterms.

The events with Warren, first reported by ABC News, will also feature Wisconsin's Democratic senator, Tammy Baldwin.

Baldwin, Evers, Kaul and Warren will host an early voting event focused on young people near the campus of the University of Wisconsin at Madison, according to the Wisconsin Democratic Party.

Baldwin and Kaul are expected to walk with a group of students to an early voting location to cast their ballots.

Barnes is in a tight race to defeat incumbent Sen. Ron Johnson, a Republican.

Polling shows that Evers is in a toss-up race, too, against Republican challenger Tim Michels, with the latest FiveThirtyEight average showing Evers with less than 1% lead.

In a statement to ABC News, the Wisconsin Democratic Party Chair Ben Wikler said: "This election is deadlocked, and no one can sit this out. If Wisconsin students turn out to show the GOP they won’t let them trample on their rights, Democrats will win up and down the ballot. Senator Warren is an electrifying voice who will bring her incomparable energy and vision to mobilize Wisconsin students at exactly the moment it’s needed most."

In her own statement, Warren said, "Voters in Wisconsin know what is at stake in this election. Wisconsinites have the opportunity to vote for [Senate nominee] Mandela Barnes, Tony Evers, and Democrats all the way down the ballot who will fight to restore a woman’s right to choose, to bring down costs, to build an economy that works for all of us, and to attack the climate crisis head on. I’m proud to join them in this critical fight."

Warren joins a growing list of big-name Democrats -- including former President Barack Obama -- to hit the trail in various battleground states before Election Day.

They hope to counter the history of rough midterm elections for the party in power, plus major headwinds like high inflation, in part by focusing on Republican-backed restrictions on abortion and the extremism of some of the GOP nominees.

When asked by reporters after a gubernatorial debate on Friday whether former President Donald Trump planned to stump for the Republican ticket in Wisconsin, Brian Fraley, a communications specialist for the Michels campaign, said they would notify the press if such an event was scheduled.

Fraley said then that Obama coming to Milwaukee was a "sign" that the Evers campaign was "in trouble" because "they're calling in all the big dogs."
