Not that I think these Democrats would be in favor of any immigration action that would result in any punishment for illegals, but they have a point here:
Rep. Zoe Lofgren, D-San Jose, blasted the Bush administration Thursday for conducting what Democrats described as harsh and punitive immigration raids, calling special attention to a raid at a kosher meatpacking plant in Iowa in May where nearly 400 illegal workers, mainly Guatemalans, were arrested in the largest worksite immigration raid in U.S. history.
[. . .]
Lofgren and other Democrats on the panel accused the administration of targeting workers instead of employers in what has become a major enforcement crackdown on illegal immigration since the collapse last year of a comprehensive immigration overhaul that would have eased legalization requirements. The overhaul was backed by President Bush and most Democrats, and opposed by most Republicans. It died in the Senate in June 2007.
It would be like rounding up hundreds of drug users and not taking action against the pusher.
