Buttigieg's senior messaging adviser, Larry Grisolano, who held the same position in Obama's 2007 campaign, drew the comparison in a fundraising email to supporters ahead of Friday's Liberty and Justice Celebration in Des Moines.

"Voters yearned for change, for someone genuine and sincere," Grisolano wrote. "They were well aware of the country’s mounting challenges, and they were prepared to take a chance on a new approach and new leadership because the same old ways just were not working."

He then cited Obama's speech at the event, calling it "the moment that changed everything for the Obama campaign and, ultimately, for the country."

"That same moment for Pete, and for America, is this Friday night," he continued.

Obama's address at the Iowa dinner was largely seen as a turning point for the campaign before the then-Illinois senator went on to win the 2008 Iowa caucuses.

While Buttigieg has struggled to break out of the Democratic primary's middle tier, recent polling shows some hope for the Midwestern mayor in the Hawkeye State.
