…and can someone with some insight into the Democratc mind explain Sheldon Whitehouse’s voting pattern to me?
The Associated Press is reporting that the Senate’s version of a comprehensive immigration reform bill is in trouble because of an amendment passed late last night…

A fragile compromise that would legalize millions of unlawful immigrants risks coming unraveled after the Senate voted early Thursday to place a five-year limit on a program meant to provide U.S. employers with 200,000 temporary foreign workers annually.
The 49-48 vote came two weeks after the Senate, also by a one-vote margin, rejected the same amendment by Sen. Byron Dorgan. The North Dakota Democrat says immigrants take many jobs Americans could fill.
The reversal dismayed backers of the immigration bill, which is supported by President Bush but loathed by many conservatives. Business interests and their congressional allies were already angry that the temporary worker program had been cut in half from its original 400,000-person-a-year target.

The amendment is potentially a poison pill because it alters the fundamental balance of the immigration compromise between our nation’s business and political elites. The deal is supposed to be that business gets cheap labor in return for Democrats getting new voters. However, the business lobby and their Republican clients (or is it the Republicans and their business lobby clients?) will be less inclined to support this bill if the Senate reduces the amount of cheap labor made available without reducing the number of potential new voters eligible to traverse a “path to citizenship”.
Senator Arlen Specter has indicated that the amendment may be amended in some way to restore the previous compromise, so this is far from over.
On the local front, Senator Jack Reed voted with most Democrats in favor of the five-year limit on the guest worker program, i.e. to create new voters for his party without giving business the expanded cheap labor pool that it wants. Senator Sheldon Whitehouse was one of the 11 Democrats who voted against the amendment. The always-alert Mickey Kaus notes that Senator Whitehouse’s vote on this is a flip-flop, as he voted in favor of virtually the same amendment on May 24. (A cynic would ask what the Kennedy machine offered Senator Whitehouse in order to get him to change his vote.)
Finally, both Democratic Presidential frontrunners in the Senate voted in favor of the amendment, bolstering the theory that this may be intended by some Dems to kill a bill that is tremendously unpopular in the country…

A Rasmussen Reports poll conducted Monday and Tuesday night found that just 23% of voters now support the bill while 50% are opposed,

…without taking direct responsibility for it. Seeking ways to take action without taking responsibility does seem to be standard Democratic party operating procedure in this session of Congress.
