If he supoports an enforcement only bill, that is 180 degrees from the arguments he made since I’ve been paying attention.
His letter dated July 17th says nothing about enforcement only. The final paragraph reads: "I have been working with many of my colleagues, as well as President Bush, to pass legislation to fix our broken immigration system. On May 21, 2007, the Senate began consideration of comprehensive immigration reform. After weeks of debate, a procedural vote to advance the legislation failed by a vote of 46-53. Although the Senate was unable to conclude its debate on the immigration bill, I will continue working to enact comprehensive immigration reform legislation because I consider it to be critical to our national security efforts." Highlight mine.
That doesn't sound like enforcement only to me.
