Is Barack Still the "unlikely" President?

Obama sells himself as the "unlikely" candidate. His message of optimism - compared to Clinton's subtle fear mongering - at a time when a significant majority of Americans are anything but optimistic makes for good sound bites.

But it will be Obama's ability to continue to reach out beyond the traditional Democratic base, as he was so successful in doing in Iowa, that will determine who wins New Hampshire and whether he can gain enough momentum to beat back Clinton in the big-state primaries where the party machines will turn out Hillary supporters in droves.

Like Obama, Clinton has campaign organisations in all 50 states. Unlike Obama, she has had to revamp her game plan since Ms Inevitable flopped in Iowa.
