The first test to the fragile Senate compromise on immigration reform came in a vote on Tuesday. Scrapping the guest worker provision would have rocked the boat too far and could have brought the fragile compromise to a collapse. Tuesday's vote, however, doesn't rule out the possibility to curtail the guest worker program to 200,000 a year, as proposed by Democratic Senator Jeff Bingaman of New Mexico. The New York Times has the full story on the vote and predicts more controversy once Senators return from their Memorial Day recess.
