On the Democratic side, Hillary Clinton today holds a 33-point lead over Barack Obama, and a 42-point lead over John Edwards. Those results are here. A couple of crosstabs of significant interest there are the gender and the party affiliation ones, excerpted here:

• Among women, Clinton holds a 42-point lead over Obama, and a 53-point lead over Edwards. Among men, it’s a 16 and 24-point lead, respectively.
• Edwards performs about twice as well — 16% vs. 9% — among Democrats as he does among unaffiliated voters.
• Obama runs more than 50% better — 31% vs 20% — among unaffiliated voters as he does among Democrats.
