Hillary versus Barack....

Something else I'm betting we will see much more on, similar to this Washington Post article:

Three differences and three similarities will define the contest between Hillary Rodham Clinton and Barack Obama.

The most important difference lies in where their respective political journeys began. After her early work as an advocate for children, Clinton came to political maturity in the South as part of her husband's efforts to rescue the Democratic Party from its low point in the 1980s. She was shaped by her party's need to win back moderate and conservative voters who had strayed to Ronald Reagan's banner.

Obama, by contrast, began his political life as a community organizer in inner-city Chicago. His earliest experiences were of a bottom-up politics mobilizing the poor and the marginalized. This had the paradoxical effect of giving some of his ideas a decidedly progressive and activist tilt and others a more conservative tinge.

And of course the almost requisite paragraph on the "firsts":

And the woman who would become the nation's first female president and the man who would become its first African American president know how important the men and women of the white middle class will be to the outcome of the next election. Such voters will probably determine if either of them gets to become a national trailblazer -- and also if any other Democrat can find a way to get in the middle of their fight.
