The Democrats' Race to Super Tuesday

A week from tomorrow, coast to coast, and with everything on the line, the biggest day of presidential primary voting in American history will take place. On Super Tuesday, February 5th, nearly two dozen states are in play — and big ones.

The Democrats are thundering for the big day. Barack Obama is fresh off a huge win in South Carolina, with big Kennedy clan endorsements. Hillary Clinton is dug in deep, with husband Bill still blasting away.
