From the article:
Indiana Gov. Mitch Daniels joined the march of would-be GOP presidential hopefuls offstage Sunday in a dead-of-night decision that put his supporters in play and muddled the fight for front-runner status against President Barack Obama. Daniels' exit, which he said he made at his family's behest, clears the upcoming news cycle to absorb former Minnesota Gov. Tim Pawlenty's entry into the race Monday in Iowa.
I think all of this is potentially related to Mitch Daniels' divorce from his wife and his family being terrified, as they should (remember the Sarah Palin stalking by reporters?), from the media attention that would surround them if Gov. Daniels decided to run for President.
