Builders are pro-illegal immigration?

That seems to be the case.

Update 12/17/2007: I just came across this story in the Washington Post:

A broad coalition of Virginia business interests, including some of the most powerful trade groups in the state, has created an organization to oppose laws that would punish employers with undocumented workers on their payrolls.

Virginia Employers for Sensible Immigration Policy was formed in anticipation of another flurry of legislation in the General Assembly seeking to crack down on undocumented residents and employers that hire them, business leaders said. Individual trade groups and companies have spoken out before about specific anti-illegal immigration proposals, but the new group is the business community’s most visible and organized effort to influence the immigration debate.

The list of those comprising the coalition is here (archived: 2008); notably the Homebuilders of Virginia is a member of the coalition.
