Yuppie janitors for Dean?

The Note quotes an 'SEIU local leader saying "Dean's style on his campaign has impressed a lot of the powerhouse locals that hire 'yuppies' and college educated, motivated and dedicated organizers. Obviously, those hires have moved SEIU into no. 1 in union membership. The connection is very 'cultural.' I mean Dean groupies look exactly like many new hires at SEIU, so the fit is interesting. If SEIU can pull off some African-American and Latino worker support, Dean's camp looks great for the election in some key states. But getting the rank and file energy around Dean may be a challenge. We will see.'"

(my emphasis above)

Wasn't this endorsement supposed to be about a new wave of diversity in the Dean camp? Seems like there are some mighty important "ifs" and "buts" involved to me...
