Full disclosure: 
I'm an Obama supporter.  I'm also strongly opposed to the Clintons, especially Bill, and have been since long before I knew who Obama was.  So you can take what I have to say with whatever grain of salt you wish. 

This campaign has been painful for many, on both sides, largely because sexism and racism have both reared their heads.  I think if we want to have any chance of healing the party, we need to deal with this.  I keep reading posts from Clinton supporters who are furious, some talking about staying home or voting McBush.  And I'm sure they have a right to be angry.  There is absolutely no question that sexism has played a part in dragging down Hillary's public image since Bill first ran in 92, and many of those same sexist characterizations have re-surfaced in this campaign season. 

Race, too, and racial charicatures have also played a role, starting in New Hampshire and South Carolina.  This (rightly) upset many on my side.  But we need to acknowledge that the Clinton people were called on this, and sexism was rarely acknowledged when it was found in the media and came from some online Obama supporters.  This, I assume, plays into the anger some Clinton supporters feel. 

My question is . . . what do we do now?  We need to come together.  Not only because we have had 8 years of insanity from the White House, and we have to do everything  we can to prevent another 4 or 8.  (McCain over the past two days has made it clear he intends to continue Bush's failed foreign policy paradigm) - but also because all of us, as Democrats, should recognize that sexism and racism are anathema to what we stand for.  These are the tools of the right, and for them to have erupted within our party is hurtful to everyone.   This isn't even just about this election - we have to heal these wounds or the Democratic coallition will not hold, long term. 

How do we come to terms with the fact that some but not most Obama supporters have been sexist, and some, but not most, Clinton supporters have been racist? 

I think a big part of it is for all of us to begin to try and be honest about the shortcomings of our own side - to confess them and try to move forwards.  As an Obama supporter, I recognize that in our anger at the Clintons comming out of South Carolina, we have often failed to censor our most extremist cohorts and failed to defend Hillary from unfair attacks.  But we must also try and keep our eyes on the big picture.  We have seen that sexism and racism are both alive in our own party.  This is deeply dissapointing, but it shouldn't be a surprise.  Parties are coalitions - they aim at bringing together at least 50% of the US population, and that population still struggles with sexism and racism.  Somewhere in every coalition there are going to be people who don't live up to the ideal.  But we must remember that this is the party which holds these ideals - this is the party of equality.  We have stumbled, we have tripped ourselves up.  But our noblest ambitions are still worth cherishing even if we ourselves have proven imperfect vessels for those ideals.  All of us, on both sides, I think, should try to rededicate ourselves, vocaly, to that goal. 

That's my best guess at what is needed - what do others think?  Specifically, Hillary supporters - do the above suggestions fall short for you, and if so, how?
