At MSNBC.com, an AP article about the history of Obama's vacations getting interrupted by news stories.
"According to a tally kept by Mark Knoller, a CBS News reporter long recognized by the White House as authoritative on such matters, Obama has spent all or part of 65 days on vacation, including days at Camp David. At this point in his tenure, George W. Bush had spent 120 days. That included 13 trips to his Texas ranch."
The polls are saying that Obama and the Democrats aren't doing well and won't do well in this fall's elections. But at this time in 1864, it looked a certainty that President Lincoln wouldn't be reelected, and events turned around by November to give him a second term.
