The Milwaukee Journal-Sentinel reported this morning:
After sending out mixed signals about its seriousness here, the Clinton campaign took several steps Monday that it said underscored its commitment to the Wisconsin contest. It launched its first TV ads, almost a week after Obama went on the air. It announced that former President Clinton will campaign Thursday in Wisconsin. It announced that Sen. Clinton will be in the state from Saturday night through Tuesday morning, the day of the primary.
Will the Clinton forces retreat to a last stand in Texas (shades of the Alamo) or try to duplicate the successful raid known as the Battle of Wisconsin Heights?
