Donald Trump celebrated Cinco De Mayo last week with a meal decidedly outside of traditional Mexican cuisine, and a Twitter message that many found wince-worthy — especially considering his labeling of Mexican immigrants as “rapists” early in his presidential campaign.

Trump has unprecedented low popularity with Latinos, likely due to the aforementioned “rapists” comment, and for his twin promises to begin mass deportations of immigrants and to build a giant wall along the U.S.-Mexico border. But he isn’t the first U.S. politician to stumble when attempting to reach out to Latino voters.

Brent Wilkes, the national executive director of the League of United Latin American Citizens said in an email that cultural outreach wasn’t enough.

“Serious candidates running for our country’s highest office understand that

in order to win the Latino vote they must address issues that matter to

Latinos, such as the need for comprehensive immigration reform, and improved

educational opportunities for all. Disingenuous attempts to relate to

Latinos only serve to expose a cultural ignorance that will alienate the

Latino community,” Wilkes said.
