CA Dems reject Arnold's choice for DMV head; what's it mean?

The far-lefties in the California legislature have rejected Arnold Schwarzenegger's choice to be head of the DMV, Joan Borucki.

Given their continued attempt to give California ID to citizens of Mexico and other countries, one wonders exactly what's going on here.
Senate President Pro Tem Don Perata, D-Oakland, said the nominee, Joan Borucki, had had a "very solid career with the state of California."

"(But) this is not a job for a bureaucrat," he added. "This is a job for a political leader ... someone who knows how to marshal forces of political clout to make sure we are safe."
So, they want someone to make sure we're safe... as they give legal IDs to illegal aliens.
Schwarzenegger's press secretary, Margita Thompson, accused Democrats of rejecting Borucki because of Schwarzenegger's refusal so far to sign a bill allowing illegal immigrants to get driver's licenses. Borucki also is a Democrat.

"The Democratic legislators are going to have to explain why they took out a competent, Democratic ... director purely because they are focused on getting this driver's license bill for undocumented workers," Thompson said. "It's a prime example of Democratic lawmakers playing politics as opposed to focusing on good public policy."
Maybe someone who's more familiar with this issue can weigh in with what this means. Do the Dems have their own candidate? And, is he related to Vicente Fox?
