Scenes from Iowa State Fair: Surging Warren, Harris draw big crowds

DES MOINES — Six months before Iowans will caucus on a cold February night, the race to earn their support kicked off in earnest this weekend as candidates descended on the state fair and two different forums amid an uncertain race.
Iowa Democratic voters take their role in kicking off the voting process tremendously seriously, and few are willing to commit to a candidate with certainty. Those candidates are adjusting their strategies and tactics after an initial period of trial and error.
"We're really coming to the end of the first half," said Jeff Link, a veteran Iowa Democratic strategist who is unaligned this year. "I think you're going to see people go into the locker room and make adjustments."
"People are really starting to get interested, especially after one dropped out," said Shawn Smith-Jones, who works for a legal insurance company and who backs South Bend, Ind., Mayor Pete ButtigiegPeter (Pete) Paul ButtigiegButtigieg campaign field organizers unionize Harris: Buttigieg comparing 'struggles' between black, LGBTQ communities is 'a bit naive' Poll: Trump edges Biden, trails Sanders in neck and neck match-ups MORE.
Interviews with almost two dozen Iowa voters this weekend provide a clear snapshot of the contours of the race ahead that have begun to emerge. The front-runner, former Vice President Joe BidenJoe BidenKamala Harris receives new Iowa endorsements after debate performance Watergate prosecutor says that Sondland testimony was 'tipping point' for Trump Overnight Defense — Presented by Boeing — Deal on defense bill proves elusive | Hill, Holmes offer damaging testimony | Trump vows to block Navy from ousting officer from SEALs MORE, maintains a shaky and shrinking lead. At least four other candidates have built formidable teams and earned substantial support in Iowa, and several more beyond that are preparing to seize their own moments. 
Biden has led in all but one public poll in Iowa conducted over the last seven months, but his chief rival has changed. At the beginning of the contest, Sen. Bernie SandersBernie SandersKamala Harris receives new Iowa endorsements after debate performance Wasserman Schultz makes bid for House Appropriations Committee gavel Overnight Health Care: Crunch time for Congress on surprise medical bills | CDC confirms 47 vaping-related deaths | Massachusetts passes flavored tobacco, vaping products ban MORE (I-Vt.) was polling in second place. Though he retains loyal backers, his poll numbers have slumped as Sens.

Illustrating their rise, both Warren and Harris drew larger and more enthusiastic crowds when they appeared at the Des Moines Register's Soapbox stage at the Iowa State Fair than did Biden — though Biden spoke Thursday, a weekday, and Warren and Harris spoke on a Saturday.
"We underestimate our capacity so, so badly. We've never lived up to it, but America is an idea. It's the most unique idea in the world," Biden told Iowans. "It's time to remember who in God's name we are."
A hundred feet away, voters casting their corn kernels at an entirely unscientific poll conducted by WHO-TV favored Biden by a slim margin, but few of those who voted for him said they were enthusiastic about his candidacy. 
"I like Joe Biden. I think I would prefer someone younger," said Laura Burkhalter, who works at a Des Moines art museum and cast her kernel for Warren. "It's time that we had a woman president."
Dennis Schwartz, who works for the state government in Colfax, cast his kernel for Buttigieg. Schwartz said Buttigieg is "very quick on his feet."
"I like Joe. I think he's a gentleman. I think he's past his prime," Schwartz said.
"The first three issues that they think about when they're evaluating candidates is, can you beat Trump, can you beat Trump, and can you beat Trump," said Link.
Burt Bibbons stopped by the state fair while visiting his adult kids in Des Moines, where he voted for Biden.
"I've always been a policy person, but this particular year, it's who can beat Trump. If you don't win, it doesn't matter what your policies are," Bibbons said. "My No. 1 priority is to win."
The candidates themselves recognize that priority among voters, and they have adjusted their stump speeches accordingly. Both at the state fair and at a Wing Ding fundraiser in northern Iowa, each of the candidates presented themselves as the most credible challenger against Trump, drawing only minor contrasts between each other.
"I hope they keep focused on Donald Trump and not each other," said Patty Judge, the former lieutenant governor.
At that northern Iowa event, some of the lower-tier candidates showed the potential for a breakout moment. Buttigieg, once a cautious speaker, won a standing ovation as he fired up the crowd. Sen. Cory BookerCory Anthony BookerBooker hits fundraising threshold for December debate after surge of post-debate donations Bicameral group of Democrats introduces bill to protect immigrant laborers The Hill's Morning Report - Sondland stuns; Dems pull punches in fifth debate MORE (D-N.J.) earned the loudest and most sustained applause of the night.
"This is not a referendum on one guy and one office. This is a referendum on us," Booker said. "It is time for America to rise again."
Two hours south, Biden clung to his corn kernel lead. By the end of Saturday, he had earned 24 percent of the vote, ahead of the 16 percent who preferred Buttigieg. Warren stood at 15 percent, Harris at 11 percent, Sanders at 9 percent and Booker and Rep. Tulsi GabbardTulsi GabbardDemocratic strategist laments 'low bar' for Biden debate performance Harris: Buttigieg comparing 'struggles' between black, LGBTQ communities is 'a bit naive' A forgettable debate for an exhausted nation MORE (D-Hawaii) were tied at 4 percent.
But with six months to go, none of the voters interviewed this week said they were certain to caucus for the candidate they favor today. Everyone has a list of three or more candidates they are considering.
"The reason things change is that people are paying attention," said Rob Sand (D), the Iowa state auditor who is only just tuning in himself. "There is a real sense of responsibility here that I think is unique to Iowa."
