"You've been there from the beginning," Giuliani said, giving him a hug.
Domino seemed resigned to an imminent end to the campaign. And he said Giuliani's strategy of largely bypassing the early states and focusing everything on the Sunshine State was a mistake.
"You gotta show you can compete," he told ABC News, adding that decent showings in New Hampshire and South Carolina would have helped Giuliani immeasurably. "He didn't have to win, he just had to be competitive," Domino said. "But they didn't ask me."
When asked whether the strategy was a mistake, actor Jon Voight -- who endorsed and traveled with Giuliani throughout Florida -- said, "There will be time to assess all that after today, and maybe it should be assessed."
In Broward County headquarters, Giuliani grabbed one of the cell phones volunteers were using for phone banking.
"Javier asked me to call and see if you'd go out and vote for me," Giuliani said to the voter on the other end. "You will?"
He sounded almost surprised.
Just a few feet away, two Giuliani supporters -- matronly women from the area -- were conspicuously talking about whom they would support next.
"Romney's better than McCain," Diane Bee, a Coconut Creek resident and a member of the Broward County Republican Party, told Egle Calvino of Coral Springs. "I don't know what I'm gonna do if that McCain gets in there!"
Giuliani started the day with his suit jacket off, in Sunny Isles Beach, at a diner called Wolfie Cohen's Rascal House. He had some coffee and raisin bran.
"I voted already," Jane Weintraub, a transplanted New Yorker, told Giuliani.
More than 440,000 Florida Republicans have already voted through early voting and absentee ballots. Giuliani's campaign banked on those early votes, which started a few weeks ago, before his plummet in Florida polls was apparent.
But ultimately those early ballots didn't mean bupkes, or beans.
