Democratic presidential candidate and former vice president Joe Biden launched an eight-day, eight hundred mile blitz through the state of Iowa this weekend. Yet the former vice president's advisers reject any characterization of the 18-county swing that was beginning Saturday as a campaign reset, even with polls showing that Biden's standing in Iowa has slipped in recent months.
Biden's aides acknowledge that he must sharpen his pitch before the February 3 caucuses that launch Democrats' 2020 voting. Conversations with advisers and supporters reveal a quiet confidence that the 77-year-old candidate retains a broad base of support and is well-situated to recover lost ground.
His chief argument - his perceived strength against Mr Trump - was on clear display last Saturday.
Public opinion polls show Biden's one-time double-digit lead in Iowa has disappeared, and he is now fighting U.S. Senators Elizabeth Warren, Bernie Sanders, and a fast-rising Pete Buttigieg, the 37-year-old mayor of South Bend, Indiana.
However, the campaign slogan has left some people baffled while others suggested it showed that Mr Biden was out of touch with younger voters. The senators have animated the party's left flank, while Buttigieg joins Biden in Democrats' center-left wing but is calling for generational change.
Thus far, Mr Buttigieg, Ms Warren and Mr Sanders have drawn consistently larger Iowa crowds than Mr Biden, while some party activists criticised his campaign as insufficiently aggressive.
Although Mr Biden's strong support in the African-American community has helped him build a dominant lead in the fourth-voting state, South Carolina, a poor performance in both Iowa and New Hampshire could derail his path to the nomination.
Mr Biden often harks back to his role as vice-president to Barack Obama and he notably used the phrase to dismiss Paul Ryan in a 2012 Vice Presidential debate, emphasising his reputation as straight-talking "Uncle Joe". They pointed to rural areas and Iowa's growing minority population that, while small, could prove important with many candidates dividing the overall caucus vote.
Another Biden volunteer, Phyllis Hughes Ewing, said outside media underappreciated Biden's appeal. "I'm on the phones with voters two nights a week for several hours at a pop".
The bullishness leans heavily on the way caucus votes are counted. Biden's team believes he'll be viable in every one of the 1679 precincts on caucus night, a reach other leading candidates may not match. Then, they believe Biden will be a top beneficiary of "realignment" votes - subsequent ballots that allow voters who supported a nonviable candidate to choose another who's still standing. First, top contenders like Warren or Buttigieg whose support might be anchored in more liberal cities and suburbs would get no practical benefit from first-ballot votes in more rural precincts where they fall short of 15 per cent. Second, several of the lower tier candidates running as moderates - Minnesota Sen.
Biden won the endorsement of the International Association of Fire Fighters at the outset of his campaign, and the organization already has tapped its locals across the state to canvass.
Harold Schaitberger, the firefighters' national union president, compared the dynamics to 2004, another primary fight when Democrats were desperate to oust a Republican president.
Schaitberger smiled as he recalled a newspaper headline in late fall of 2003: "Kerry dead in the water".
