CAPITOL HILL -- With four more votes than needed, the Senate has revived the immigration bill. The final tally in the pivotal test-vote was 64-35.
The bill would legalize millions of undocumented workers and at the same time beef up borders.
An optimistic President Bush said earlier today that he expects the bill to pass through the Senate by the end of the week. He says it offers a "historic opportunity" for Congress.
There are still some formidable obstacles, including a bloc of GOP conservatives bent on stopping the bill. And lawmakers in both parties want to revise some of its key elements.
The legislation could be facing its next major test as early as Thursday.
A similar test-vote earlier this month found just 45 supporters.
