I feel similarly. I went looking for someone with the guts to say that freedom of religion was important, and meant that the state should not be run by a church. All I found was Kucinich (whose earlier views on the abortion issue were horrifying to me, but he did at least go talk to a bunch of women and find that he couldn't support it becoming illegal after looking for input from the people most likely to be affected), who also hasn't got a snowball's chance of being elected.

Since that's pertinent to your current search on candidates with an eye on Constitutional rights, I'm willing to see if I can find it again in the morass that is the internet election collection, if you'd like to read it. Otherwise, I'll spare you the link, and me the search.
