Basically, if you are somewhat successful and educated, you voted for Obama. If you were poor and/or didn't have a college degree, you voted for Hillary according to the stats. Geeeeeeeeeeeee, who would have thought? 
How Clinton Won
 Hillary Clinton won last night by putting together the voting coalition that has held Democratic frontrunners in good stead for 75 years. Take a look at these numbers - all of which come from CNN's cross-tabulated exit polls.  What you'll see is that Hillary Clinton won many elements of the traditional  FDR coalition.-Self-identified Democrats made up 54% of the electorate.  She won them, 45% to 34%.  
-She won voters without a college degree, 43% to 35%.
  -She won voters with incomes less than $50,000, 47% to 32%.  
  -She won voters over the age of 65, 48% to 32%.  She also won voters in their 40s (44% to 33%) and their 50s (39% to 30%).
  -She won Catholics, 44% to 27%.
  -She won urban voters, 43% to 35%.  She won suburban voters, 42% to 31%.
  -She won voters from union families, 40% to 31%.
  -She won voters who said they have been "falling behind" economically, 43% to 33%.
  -She won long-time voters, 38% to 33%.
Obama, on the other hand, had a very different electorate - one that has a bit in common with the insurgent candidacies of Gary Hart and Bill Bradley.-He won Independents, 41% to 31%.  
-He won voters with at least a college degree, 39% to 34%.  
  -He won voters who make more than $50,000, 40% to 35%.
-He won college age voters, 60% to 22%. He split voters in their late 20s, 35% to 37%. He won voters in their 30s, 43% to 36%.
  -He split Protestant voters, 36% to 36%.
  -He won rural voters, 39% to 34%.
  -He split voters from non-union households, 39% to 38%.
  -He won voters who said they were "getting ahead" economically, 48% to 31%.
  -He won first time voters, 47% to 37%.
An additional ingredient to Clinton's success was a victory among female voters, 46% to 34%. Obama won male voters, 40% to 29%. But female voters outvoted male voters, 57% to 43%.
