"It's a very busy time, certainly, but we've got to take care of the business of the party and make sure we get Governor Romney nominated," Luckey said. "We have a lot of work to do between now and November."
Vice presidential candidate Paul Ryan decided to head to Florida on Tuesday, a day later than expected. He was in his hometown of Janesville, Wis., on Monday putting final touches on his convention speech and addressing students at his former high school. Signs at the school proclaimed him "The pride of Janesville."
The storm was a complication, at best, for a party determined to cast the close election as a referendum on Obama's economic stewardship and Romney as the best hope for jobs and prosperity.
The concern was two-fold: that Tampa, hosting thousands of GOP delegates, would get sideswiped by the storm; and that it would be unseemly to engage in days of political celebration if Isaac made a destructive landfall anywhere on U.S. soil.
"You can tone down the happy-days-are-here-again a bit," said Rich Galen, a veteran Republican consultant in Washington. "Maybe you don't have the biggest balloon drop in history."
In Washington, aides said Obama was being updated at the White House on the storm. He was still planning his two-day campaign trip to Iowa, Colorado and Virginia, beginning Tuesday morning.
In a boost to Obama's convention next week, Florida's former Republican Gov. Charlie Crist was added as a speaker. Crist had announced on Sunday that he was endorsing Obama, saying he was the correct choice and criticizing his former party for its move to the right.
For all the weather concerns, a mix of partly sunny skies, fast-moving clouds and occasional rain covered Tampa at midmorning Monday as the outer bands of the tropical storm delivered unsettled conditions.
Traffic was light as streets around the arena were blocked off and security patrolled the area.
The roll call of state delegations affirming Romney as the party's nominee now is to unfold Tuesday, an evening capped by speeches from Ann Romney and an assortment of GOP governors. Ryan gets the prime-time spotlight Wednesday, and Romney closes out the spectacle Thursday night, his springboard into the final leg of the contest. That's all if the storm brings no further complications.
Polls find a tight race, and it's one that is likely to be settled in a small number of battleground states.
Republican office-holders past and present say the economy is the key if Romney is to expand his appeal to women and Hispanic voters.
"We have to point out that the unemployment rate among young women is now 16 percent, that the unemployment rate among Hispanics is very high, that jobs and the economy are more important, perhaps, than maybe other issues," said Arizona Sen. John McCain, who lost to Obama in 2008.
The Romney campaign released a Spanish-language radio ad with son Craig's testimonial to his father.
