ashtag “grabyourwallet” began calling on women across the United States to shun clothes and shoes designed and marketed by Ivanka Trump.

　　To those who have purchased Ivanka Trump’s signature products, the message has been either return them for a refund or, if that’s not possible, burn them as a protest against the designer’s support of her father during the presidential campaign.

　　Donald Trump’s brands have been tarnished as well, with travel sites such as Hipmunk reporting a decline in business at his hotels and research group Brand Keys noting reduced sales of clothing and watches branded with his name.

　　The Trump Organization has denied any decline in business caused by the months of fiery political exchanges, and a corporate press release quoted Ivanka Trump as saying, “Our business at Trump Hotels is stronger than ever.”

　　However, Trump executives also have announced they will be rebranding the group’s hotels in the future. Lodgings that were Trump will become Scion Hotels, a name chosen because it means “descendant of a notable family,” according to the news release announcing the new company.

　　But hard numbers on how much sales of Trump items have declined are hard to establish, and the campaign’s long-term effects on the brand are yet to be seen.

　　“We don’t have any precedent with this,” Oates said. “The future will have to say what effect running for president has on your brand.”

　　Clinton in Florida

　　Clinton, campaigning in the key battleground election state of Florida, went to the Adele concert Tuesday, where the pop artist endorsed her candidacy even as she acknowledged she can't vote for her because she is a British citizen.

　　Clinton is in Florida again on Wednesday, her 69th birthday. The 70-year-old Trump spent two days this week visiting seven cities in the state.

　　He acknowledged he has almost no chance of winning the election if he does not carry Florida, where 29 electoral votes are at stake.

　　Battleground states

　　The U.S. elects its presidents through contests in each of the 50 states and the national capital, Washington, with the most populous states, Florida among them, having the biggest influence on the outcome, rather than through a national popular vote. An average of recent polls in the state shows her with a 1.6-percentage-point edge, but the most recent survey has Trump ahead by 2 percent.

　　The overall national winner needs a majority of 270 electoral votes in the 538-member electoral college. At the moment, numerous polling analysts say Clinton has enough of an electoral college cushion to claim the presidency. But several state contests are close, with Trump in striking range of overtaking her in key states that could yet overturn Clinton's expected victory.

　　Her national polling edge over Trump has slipped in recent days to about four percentage points, about two points closer than it had been, and some of the state-by-state contests have narrowed, too.

　　But Trump continues to face resistance to his campaign from Republicans who normally have supported their party's presidential nominees.
