“Hillary Clinton will at some point announce her decision about whether or not to run for president in 2016. That decision -- after careful deliberation spanning a period of several minutes -- will be that she has decided to run. And if history is any guide, that announcement will happen in about 99 days.”
“Since 1988, there have been five announcements that took place in the same year as midterms: Howard Dean in 2004, Bill Bradley in 2000, John Kerry in 2004, John McCain in 2000, and John Edwards in 2008.”
Note: Tom Vilsack formed an Exploratory committee on November 9, 2006 and announced on November 30, 2006.
