It's perfectly legit to compare the trips she has taken or her staff size to previous first ladies.
Before you get on your horse and start talking about Obama and shared sacrifice let remind you what was going on during GWB administration. US servicemen were getting killed in Iraq at an alarming rate, the families of National Guard and Reserve servicemen were under severe financail strain. Never mind the fear of hearing a car pull up in their driveway. How many trips off the tax payer dime did GWB's family take while this was going on? See, two can play this silly little game.
Silly little game? Does America expect their President to hunker down in a bunker?
Bush had his Crawford Tx Whitehouse I believe, Clinton did Camp David....as well as Bush.....if you check, I think 'O' shot the lock off.
Granted casualties were high in the early Iraq years......but was Bush on vacation more or less than the Chosen One?
Silly little game....
