Do you know what extension he's on? teen nipples Obama joins a long list of presidents who have been criticized for their vacation habits, which I describe in my book "From Mount Vernon to Crawford: A History of the Presidents and Their Retreats." But he has taken far fewer vacations than his predecessor, according to CBS News' Mark Knoller, who chronicles presidential travel. Obama had taken 14 vacation trips for 92 days before his current vacation started. At a similar point in George W. Bush's presidency, he had visited his Texas ranch on 50 trips for 323 days, and that number doesn't include several weeks on other vacation trips. Some critics say Obama has a taste for more expensive jaunts than Bush did, but the government has not given a full accounting of the costs.
