The Connecticut Citizens for Immigration Control did a bit of a study and determined that most employees of McDonalds in America's drive-throughest state are Hispanic. The study is available at their website in a PDF file, and it's not exactly an academic study, although it appears they visited all or almost all the Mickey D's in the state, many in one long day. (Here's a similar feat involving CT's county highpoints). They counted the people working there, and they wonder whether some of them are illegal aliens. In New Haven and Fairfield counties, almost all the employees are Hispanic.

A news report is wtnh . com/Global/story.asp?S=3914094:

But activists say his research methods were unsound and motivated by racism. Attorney General Richard Blumenthal has rejected Streitz's call for an investigation, saying the study is not reliable or relevant.

Obviously, the race baiting can and should be ignored. As for whether the study is unsound, I personally don't consider it an academic-level study. Also, there's the question of whether all the workers are Hispanic because managers want that, or because they are the only applicants.

That would need to be determined through other means, and I get the impression that Blumenthal is too PC to conduct such an investigation.

For that, I'd suggest contacting that state's Senators or Reps and encourage them to look into this.
