President Obama’s Vacation Days | FactCheck.org
Do you think Bush 2's numbers should be higher? They are if Camp David is included, but I think it is reasonable to exclude Camp David as the list I posted did. Do a search. As always, truth is often different than perception. Hard to evaluate how hard or how much a president is working when we have no idea what any particular day, week, or month looks like. I have no problem with people having real issues with a particular president, but the vacation/recreation discussion holds no water when it is fairly compared to all presidents.
