DUBUQUE, Iowa -- At a packed eastern Iowa house party, a staffer for Democrat Beto O'Rourke's presidential campaign tried to clear enough space for the candidate to reach the kitchen, where he would need to climb a stepladder to address the crowd.
"I need my lane," the staffer bellowed as he moved through the crowd. "Beto's coming right through here."
Somewhere in the rows of pressed-together faces, a spectator quipped: "But which lane is it? The liberal lane? Some other lane?"
The architects of his campaign insist he's not interested in adhering to a particular ideological lane, and O'Rourke himself shuns party labels. But trying to have it both ways could leave Democratic voters with the impression that O'Rourke is a candidate with a split political personality.
"I see him as offering Rorschach politics," said Norman Solomon, a Bernie Sanders delegate to the 2016 Democratic National Convention from California. "In the age of Trump, when you want to be something for everybody, you're going to end up being amorphous for a lot of people."
Backers say O'Rourke can and should toggle between liberal and moderate positions depending on the topic.
"If there's an issue he might be more centrist on, he's honest about that. He doesn't try to pander to a certain base," said Rep. Kathleen Rice, D-N.Y., who endorsed O'Rourke over another, home-state Democrat in the race, Sen. Kristen Gillibrand.
As a presidential candidate, O'Rourke has moved more to the center than he did last fall, when he nearly upset incumbent Sen. Ted Cruz, R-Texas. O'Rourke had called for impeaching Trump but has since backtracked. He once endorsed Sanders' "Medicare for All," but now backs a more moderate House plan known as "Medicare for America."
"It's got to be all of us, not just Democrats, not just Republicans," O'Rourke repeats while campaigning. "I'm running for president for every single state in the United States of America and every single person in every single one of those states."
"We can't just be nice to Republicans," said Solomon. "We know that doesn't work."
O'Rourke has deviated from messages of moderation by expressing openness to adding justices to the Supreme Court and tearing down U.S.-Mexico border walls in places like his hometown, El Paso. He's also equated the criminal justice system to modern day Jim Crow laws because he says it's so much tougher on people of color.
And O'Rourke has championed the "Green New Deal," liberal Democrats' sweeping plan to combat climate change, and a federal assault weapons ban, though he concedes that current owners of AR-15 rifles should be allowed to keep using them "responsibly and safely."
It's all a far cry from when O'Rourke arrived to Congress in 2012. Though he called for the federal legalization of marijuana long before much of the rest of the country began to turn on the issue, O'Rourke pledged to be pro-business and joined the New Democrat Coalition rather than the Congressional Progressive Caucus. He'd also said he would support raising the Social Security eligibility age and basing eligibility on recipient income.
O'Rourke refused to back Nancy Pelosi's House minority leader bid in 2016, dismissing her and Senate Democratic leader Chuck Schumer of New York while campaigning against Cruz for misunderstanding Texas. But Pelosi had only kind words for O'Rourke last week, calling him a "welcome addition" to the 2020 primary.
He also drew criticism from home-state Democrats for failing to endorse Gina Ortiz Jones, who was trying to unseat Republican Rep. Will Hurd in November. Hurd lives outside San Antonio and when a 2017 snowstorm canceled flights to Washington, he and O'Rourke drove from Texas to the nation's capital, livestreaming for hours and developing a friendship that some celebrate as a rarity in such hyperpartisan times.
But Democrat MJ Hegar, who nearly defeated Republican Rep. John Carter in a suburban district outside Austin and may challenge him again in 2020, pointed to that bond as an example of how O'Rourke and other members of Congress' "good ole boys club" were "looking out for your bros more than fighting for your values."
Rice counters that the party doesn't have to agree on everything.
"The last thing the Democrats need to do is to kill each other," the congresswoman said. "We need to remember that we're all on the same side."
