If Obama decides to take the plunge, the free ride is over. As Page noted in his please-run column, the media will turn on him like a bunch of vultures. And they won't have far to look: Obama's acknowledgment in his book of having played around with marijuana, alcohol and "maybe a little blow" may seem a bit less charmingly candid in a declared presidential candidate.
The "free ride is over" for a "declared presidential candidate"? We already have a "declared President" who everbody knows has "played around" with that stuff already.
