By JULIE HIRSCHFELD DAVIS, Associated Press Writer 41 minutes ago WASHINGTON - The Senate voted Tuesday to jump-start a stalled immigration measure to legalize millions of unlawful immigrants. President Bush said the bill offered a "historic opportunity for Congress to act," and appeared optimistic about its passage by week's end. The pivotal test-vote was 64-35 to revive the divisive legislation. It still faces formidable obstacles in the Senate, including bitter opposition by GOP conservatives and attempts by some waverers in both parties to revise its key elements. Supporters needed 60 votes to scale procedural hurdles and return to the bill. A similar test-vote earlier this month found just 45 supporters, only seven of them Republicans. This time, 24 Republicans joined 39 Democrats and independent Sen. Joseph I. Lieberman of Connecticut, to back moving ahead with the bill. Opposing the move were 25 Republicans, nine Democrats and independent Sen. Bernard Sanders of Vermont. Sen. Edward M. Kennedy, D-Mass., an architect of the bill, said he was proud of the vote, calling it "a major step forward for our national security, for our economy, and for our humanity." "We did the right thing today because we know the American people sent us here to act on our most urgent problems. We know they will not stand for small political factions getting in the way," Kennedy said in a statement following the vote.
