Amid the rush to describe the failure of immigration reform in the Senate yesterday as yet another indication of the waning influence of President Bush, allow us to mark the point that the Senate in which the bill failed to win even a simple majority yesterday is a chamber controlled by the Democratic Party. In the key vote yesterday, the Democratic majority leader, Harry Reid, failed to deliver 15 of his party’s senators — Baucus, Bayh, Bingaman, Brown, Byrd, Dorgan, Harkin, Landrieu, McCaskill, Ben Nelson, Pryor, Rockefeller, Stabenow, Tester, and Webb. These aren’t just fringe figures but include, in Messrs. Harkin, Baucus, Byrd, and Rockefeller, senior members who are committee chairmen and among the leaders of the Democratic Party’s congressional wing. Another senator who caucuses with the Democrats but who is technically an independent, Senator Sanders of Vermont, also voted against the bill. The AFL-CIO, which despite its decline remains a major interest group with the Democratic Party, opposed the legislation. At a certain point the Democrats are going to have to stop blaming President Bush and the Republicans for the lack of progress in solving important issues in Washington, because it just stops being credible. With a majority in Congress comes responsibility, and on immigration yesterday, the Democrats failed to deliver.
