Trump’s political rallies may be packed, but Trump-branded properties are increasingly empty, according to Foursquare. In analyzing data from the time that Donald Trump announced his candidacy last June to now, location technology firm Foursquare noticed a significant decrease in foot traffic to the entrepreneur’s hotels, casinos, and golf courses located in the U.S. Last month, visits to Trump’s properties’ appeared to be down 14 percent from the same time last year, with the overall decrease hovering around 10 percent year-over-year.

In looking at visits in red states versus blue states, the difference is even more apparent. His brand’s properties in New York, New Jersey, Illinois, and Hawaii have taken a dip of about 20 percent, with those facing the most significant dips being Trump SoHo, Trump International Hotel & Tower Chicago, and the Trump Taj Mahal, which is no longer owned by Mr Trump. Mr. Trump is, to be fair, doing his part to prop up the Trump property brand, spending campaign money where he can with companies that bear his surname. According to July campaign filings, Trump’s team spent over $145,000 at Trump Tower, Trump Plaza, Trump Restaurants, Trump Parc at Central Park South, and Trump National Golf Club.

The Foursquare data also highlighted that women, a demographic frequently marginalized by Trump’s campaign, contributed disproportionately to the decrease in traffic to these locations.

It’s not the first time that Trump’s politics have been linked to a dip in his business success, as Priceonomics noted that bookings at Trump hotels plummeted 59 percent in the spring.

Foursquare’s analysis doesn’t account for all those visiting Trump establishments for the sole purpose of flipping them off, a trend Vocativ noticed back in March. Several protests have also been held at Trump’s properties over the course of the past year, organized by both striking laborers and political activists, which could still be propping up the numbers .
