Fyi, Kerry and Gore pulled about the same with whites overall at about 41-42% -- and much better than Obama has been doing, at about 35%, last I saw.  So the gender difference you cite is interesting -- Gore must have done a lot better with white women than either Kerry or Obama.

Btw, your story of your mom makes me think of my ex-mom-in-law, a remarkable centenarian today who was widowed in WWII with an infant son -- yet even decades ago, and despite all she endured as well in the workplace, she managed to make it and buy a home of their own as a single mom in the '50s.  And then she had to send her only child to the Viet Nam War.  

Fortunately for her and me and our kids, that man in her life made it back.  I am so sorry about your father.

And Wisconsin has an open primary, so we saw one of those years with (widely encouraged by the GOP) a sizeable crossover, and it went for Obama.

Why?  Above all, Wisconsin was the primary after Super Tuesday, when the need for a new Clinton campaign manager became clear, as there were not plans for a serious Wisconsin campaign.  Then the primary came only a few days after the upheaval with the replacement of campaign managers for Clinton, so the campaign here began 'way too late.  

And then it got cut back to almost nothing -- no public event in Milwaukee, ever! -- because of the awful weather this winter here.  Btw, the totals now have been tallied for the winter here, anyway, and it has been the second-snowiest of all time in Milwaukee, officially, although THE snowiest in Madison -- those being the two Dem bases in the state -- and the snowiest ever in many parts of Milwaukee, such as mine.  More than ten feet of snow in total, and much of it was that darn week before the primary.  And don't even talk to me about how cold it was this winter, too.

... then see if you still believe that WI is a good predictor of the PA result. This analysis seems to suggest that SUSA is on the right track.

For further analysis of the same subject, see this:

In Terms of Geography, Obama Appeals to Academics and Clinton Appeals to Jacksonians

I'm guessing that even if Clinton gets a 10% margin, Obama will argue that he beat expectations.  Anything below 10% and Obama will claim a moral victory.

Many of those out-of-state students are registered to vote in their home states. Sean Coit, 20, a junior at Saint Joseph's University in Philadelphia and the news editor of the school newspaper, The Hawk, is among them.

Although he follows politics closely and is interning with a Democratic consultant in Philadelphia, he will not be voting in the Pennsylvania primary since he is registered to vote in Virginia at his parents' house.

"A lot [of students] are voting absentee at home," said Coit of his fellow out-of-state students.

Pennsylvania's election rules also act to suppress the college vote. The state has a closed primary, which means only registered Democrats can vote. Since college-age young people are disproportionately likely to be registered as independents, that will serve to limit the number of students who can vote.
