Regarding the recent poll that found 80% of evangelicals oppose federal intervention in the Shiavo case: I'm a bit surprised (and skeptical) that it's quite that high, but I wouldn't at all be surprised if further polls were to confirm it between 45-55%.

As I've said before, 'evangelical' is an incredibly fluid term; it presupposes neither a conservative politics nor a mindless partisanship in favor of 'evangelical' politicians.

What the poll should have examined are those who both described themselves as evangelical and claimed to have voted for Bush. Of that group, I imagine the numbers would be more in line with what conventional wisdom would expect.
