In regard to the recent letter complaining about President Obama, I think it is worthwhile to set the record straight on the matter of presidential vacations and compare vacation days taken by President Obama and those taken by his predecessor.
Politifact looked into the question and I'll quote what they found.
Related rulings: Mostly True ... Says President Barack Obama "has taken 92 days of vacation since he was sworn in, compared to 367 for President George W. Bush at the same point in his presidency." -- Al Sharpton, Aug. 9, 2013.
I think this puts the letter writer's complaints in perspective. Maybe we should thank President Obama for his dedication to doing his job.
