Certain elements of the Democratic Party are pushing for a plank in the party platform that states that the primary elections "exposed pervasive gender bias in the media" and to call on party leaders to take "immediate and public steps" to condemn future perceived instances of bias. I didn't perceive this bias, but then I'm a white male and think Senator Clinton is perfectly awful enough without worrying about her gender.
I know that women, particularly women who grew up in an era of overt discrimination against women felt that there was a strong gender bias on display in the Democratic primary. One even recently commented that if Senator Clinton is not the VP candidate she will not be able to vote Democrat this year. This is certainly something the Party should pay attention to, because this is a group who can move the election to the Republican side.
