The results of the Family Research Council's Values Voter Summit Straw Poll are a good indicator of the tastes of conservative activists. I'd expect a decent percentage of Tea Party sympathizers at the FRC summit, so the poll is probably a good indication of where conservative energy is centralized.

The interesting details are that Pence has risen to national stardom amongst conservatives, whereas Palin is seen as a viable VP - but not a ticket-header. Huckabee, of course, is still a favorite
