As Americans gear up to celebrate Independence Day tomorrow, brand marketers of all stripes are rushing to capitalize on the patriotic mood of the country. But as Robert Passikoff pointed out on Forbes.com this week, successfully leveraging a brand in this way “has always had more to do with believability via emotional brand engagement than brand awareness via ad budget.”

So which brands rank as most patriotic in consumers’ minds? Forbes conducted a brand values survey of 197 American brands to find out. Then we chose four of the brands that came out on top and ran a 30-day sentiment analysis on Topsy Pro to see how patriotism affects overall sentiment about a brand.

The results, perhaps unsurprisingly, showed that brands associated with patriotic values enjoy steadily positive sentiment. What we didn’t entirely expect: Twitter users really, really love chocolate.

Happy Fourth of July!
