Is Joe Arpaio a racist?

Is Joe Arpaio a racist? I don't know, but I would feel better if he would focus on keeping Canadians out of this country instead of the Mexicans. Look at all of the problems they have caused in the NBA and especially Major League Baseball. The Expos just about killed the league. I just found out that Joe Arpaio was the child of immigrants from Naples. Very Interesting. I have a suspicion that keeping the Mexicans out is not about race but about money. I would like to know if Joe has any interests in Mexican restaurants and is just trying to keep out the competition. I think that there is still room for Canadian restaurants.
