That should have been your clue. The Florida and SC primaries are now in January. NV moved up. If they haven't already, IA and NH will move up. That is three months away. Did you really think that she was going to start a campaign for President of the United States of America three months from the first, critically important, primaries?
Heck, people--with big checkbooks--were begging Christie to run and he still said no. Why come in now, lose, and then mess up your chances later?
Because she said she’d be running a different campaign.
