One thing you can do to make the Dems listen

I wrote my Rep today, short, to the point letter.

Dear X
I do not need to remind you that this is an election year. I voted for you last time, but I will only vote for you again if you do one of two things:

1) Publicly denounce the sexism that has been rampant during this primary season. It is an atrocity and an affront to the largest voting block of the Democratic party. You, along with the rest of the party have stood idly by and in your silence have made it perfectly clear how you feel about women. If you do not feel this way you need to say it and you need to say it now.
or
2) Take back your endorsement of Obama and endorse Hillary Clinton before June 3rd.

You may choose either of the above, but you must do something or else you will not have my vote come Novemeber.

Sincerely,
me

The local, state, and national parties may not be listening, but if the pols who need to get elected get enough of these you bet your ass they'll be listening.

NOTE: This is not to say that all Obama supporters are sexist (though if you are not speaking out, especially about his demeaning behaviour towards women (see sweetie comment, PA kiss comments, etc) you are in my book) I just threw that in, though I'm about 99.8% sure he won't.
