From RealClearPolitics:

Hundreds of angry Americans took to pouring their Absolut vodka down the drain after the company published an advertisement showing several Southwestern states as part of Mexico. Sensing an opening akin to a major gaffe on the campaign trail, SKYY Vodka has issued a press release slamming their Swedish rivals. As it turns our, SKYY supports the Treaty of Guadalupe Hidalgo.

This is from the press release, quoting a SKYY Vodka rep:

"Like SKYY Vodka, the residents of states like California, Texas and Arizona are exceptionally proud of the fact that they are from the United States of America," said Dave Karraker, SKYY Vodka. "To imply that they might be interested in changing their mailing addresses, as our competitor seems to be suggesting in their advertising, is a bit presumptuous."
