Immigration Bill Dead?

I'm watching the cloture vote live on C-Span 2 right now; if the bill's proponents can't get 60 votes, Reid will pull the bill (again). Coastal Democrats seem generally supportive, as do some interior lefties (Kohl just voted aye). I'll keep up with this one as well.

UPDATE: It's dead!! 46-53 (Johnston not voting, I suspect).

UPDATE 2: Finally got the roll call (thanks to Hotair!). Almost all of the Republicans who voted for cloture are either up for reelection, RINOS, both, or "mavericks." One of the few exceptions to this rule is Jon Kyl, whose conservative credentials are beyond criticism. I feel like his support was based on this being a somewhat workable fix and him being a border-stater.
