Dena Bunis of the OC Register offers "Democrat talks tough on illegal immigration/Key senator in upcoming debate could help sway GOP votes" (link). The "key senator" is Charles Schumer, and part of his "tough talk" was discussed here. Bunis has some more quotes and she does at least consider whether what he's just playing or not. Here's the extended Schumer quote from :

"When we use phrases like 'undocumented workers,' we convey a message to the American people that their government is not serious about combating illegal immigration, which the American people overwhelmingly oppose... ...People who enter the United States without our permission are illegal aliens, and illegal aliens should not be treated the same as people who entered the United States legally... ...Just as the American people are strongly against illegal immigration, they are also just as strongly against turning their country into a 'roundup republic,' - where they will be confronted by nightly news stories of sympathetic families being torn apart at gunpoint during harsh enforcement raids. The American people prefer a pragmatic solution that works to empty rhetoric, however satisfying, that fails."

That's the kind of "tough talk" that could convince the John McCain types that he's serious, but no one else should be fooled. The very hour after "reform" passes, the Democrats would begin working to undermine all of its tough provisions in order to gain even more power.
