Throughout Hillary Clinton's run, we heard about the sexism over and over. Already, one reporter was caught commenting on Sarah Palin's look. Now, the first thing Biden says about how he differs from Palin refers to her looks. I will be really interested to see how the Democratic ticket and the media treat Governor Palin: Will they see her first and foremost as a serious candidate or will they see her first as a woman? This will be the challenge and will tell us a lot about where we are today.
