Elizabeth has stepped back a bit from yesterday's statement that she has more confidence in Hillary Clinton than Barack Obama on the issue of health care, saying instead that she and John Edwards could be best effective at this point as "honest brokers" on issues they care about, rather than endorsing any candidate.

She also denied that a reported conversation with Barack Obama turned them off from his candidacy, but did acknowledge some differences: "And where there are differences, we talked about those differences and why I believed John's was right."
