[edit] a little Cinco de Mayo snark...
In an attempt to salvage momentum lost from their failed "Teabag the White House" movement, conservatives are using Cinco de Mayo as an anti-Immigrant platform. The Mexican holiday, which is Spanish for May 5th, has drawn fire from conservatives who fear the Swine Flu pandemic. Austin, Texas "Hold the Mayo" organizer Jed McIntyre said something needed to be done. "We knew that American jobs were being taken by Mexicans, but now that they’re bringing in that Swine Flu, our lives are under attack too. Cinco de Mayo is Mexican, therefore a threat and we will boycott Mayonnaise from May 5th until our borders are secure."
