I couldn't find any similar transcripts from Dean but was able to find this on the DNC website:

"As Chair of the Democratic Party I join millions today in celebrating Cinco de Mayo, and the victory for freedom and liberty this day represents. Cinco de Mayo commemorates the battle at Puebla in 1862 when Mexican soldiers defeated an invading imperial force more than twice their size.

"Cinco de Mayo has become part of our cultural heritage in the United States, and a reminder of the contributions Mexican-Americans have made to our social, economic, and cultural identity. As Democrats we share the faith, work ethic, and family values that have made the Mexican-American community strong.

"The shared history we celebrate today stands in stark contrast to the failures and broken promises of the Republican administration in the White House. Mexican-Americans, and Hispanics in general, have seen economic opportunity crumble under the Bush administration, and more and more Hispanics do not have access to health insurance. Hispanics would see thousands of dollars per year slashed from their hard-earned Social Security benefit checks if the President’s privatization scheme were in place today. And rather than promoting immigration reform to bring millions of hard-working undocumented workers out of the shadows, President Bush has sided with extremist anti-immigrant Republicans by supporting such extreme measures as Real ID.

"This Cinco de Mayo the Democratic Party remains committed to increasing economic opportunities, making health care affordable and accessible, and protecting Social Security for every American. We will continue to fight for comprehensive immigration reform that both recognizes the hard work of immigrant families, and improves our homeland security. Mexican-Americans have been instrumental in building up the Democratic Party throughout its history, and together we will continue to work for a better future and a stronger America."

The speches are like night and day, water and oil. Republicans seek to integrate and assimilate while Democrats seek to segregate and instigate.
