You may have read some of these excerpts from the book IN THE PRESIDENT’S SECRET SERVICE - a candid account of the last many presidents and their wives – and NO surprises really. 
No big surprises, except for the Carters.....I had always thought they practiced what they preached. Just goes to show, you never know. But I do believe the Secret Service knows the real details about all of the presidents and families. 
White House Guests 
Here are snippets from a book of "Impressions & Observations" of 
Secret Service personnel assigned to guard U.S. Presidents/First 
Ladies, and Vice Presidents.
JOHN & JACQUELINE KENNEDY : *A philanderer of the highest order.* 
*She ordered the kitchen help to save all the left-over wine during 
State dinner, which mixed with fresh wine and served again during the 
next White House occasion.* 
*LYNDON & LADYBIRD JOHNSON *Another philanderer of the highest order. 
In addition, LBJ was as crude as the day is long.* 
*Both JFK and LBJ kept a lot of women in the White House for 
extramarital affairs, and both had set up "early warning systems" to 
alert them if/when their wives were nearby. Both Kennedy & Johnson 
were promiscuous and oversexed men. * 
*She was either naive or just pretended to "not know" about her 
husband's many liaisons. * 
*RICHARD & PAT NIXON ** * 
*A "moral" man but very odd and weird, paranoid, etc. He had horrible 
relationship with his family, and in a way, was almost a recluse.* 
*She was quiet most of the time.* 
*SPIRO AGNEW:** Nice, decent man, everyone in the Secret Service was 
surprised about his downfall. * 
*GERALD & BETTY FORD: ** * 
*A true gentlemen who treated the Secret Service with respect and 
dignity. He had a great sense of humor. * 
*She drank a lot!* 
*JIMMY & ROSALYN CARTER: ** * 
*A complete phony who would portray one picture of himself to public 
and very different in private, eg., would be shown carrying his own 
luggage, but the suit cases were always empty; he kept empty ones just 
for photo op's. Wanted the people to see him as pious and a 
non-drinker, but he and his family drank alcohol a lot. He had disdain 
for the Secret Service, and was very irresponsible with the "football" 
nuclear codes. He didn't think it was a big deal and would keep 
military aides at a great distance. Often does not acknowledge the 
presence of Secret Service personnel assigned to serve him.* 
*She mostly did her own thing.* 
*RONALD & NANCY REAGAN: ** * 
*The real deal --- moral, honest, respectful, and dignified. They 
treated Secret Service and everyone else with respect and honor. 
Thanked everyone all the time. He took the time to know everyone on a 
personal level. * 
*One "favorite" story which has circulated among the Secret Service 
personnel was an incident early in his Presidency, when he came out of 
his room with a pistol tucked on his hip. The agent in charge asked: 
"Why the pistol, Mr. President?" He replied, "In case you boys can't 
get the job done, I can help." It was common for him to carry a 
pistol. When he met with Gorbachev, he had a pistol in his briefcase. 
Upon learning that Gary Hart was caught with Donna Rice, Reagan said, 
"Boys will be boys, but boys will not be Presidents." [He obviously 
either did not know or forgot JFK's and LBJ's sexcapades!]* 
*She was very nice but very protective of the President; and the 
Secret Service was often caught in the middle. She tried hard to 
control what the President ate, and he would say to the agent "Come 
on, you gotta help me out." 
The Reagans drank wine during State dinners and special occasions 
only; otherwise, they shunned alcohol; the Secret Service could count 
on one hand the times they were served wine during their "family 
dinner". For all the fake bluster of the Carters, the Reagans were the 
ones who lived life as genuinely moral people.* 
*GEORGE H. & BARBARA BUSH: *Extremely kind and considerate Always 
respectful. Took great care in making sure the agents' comforts were 
taken care of. They even brought them meals, etc. 
*One time Barbara Bush brought warm clothes to agents standing outside 
at Kennebunkport ; one agent who was given a warm hat, and when he 
tried to nicely say "no thanks" even though he was obviously freezing, 
President Bush said "Son, don't argue with the First Lady, put the hat 
on.." He was the most prompt of the Presidents. He ran the White House 
like a well-oiled machine.* 
She ruled the house and spoke her mind.* 
BILL & HILLARY CLINTON: **Presidency was one giant party. Not 
trustworthy --- he was nice because he wanted everyone to like him, 
but to him life is just one big game and party. Everyone knows of his 
sexuality.* 
She is another phony. Her personality would change the instant cameras 
were near. She hated with open disdain the military and Secret 
Service. She was another one who felt people are there to serve her. 
She was always trying to keep tabs on Bill Clinton.* 
ALBERT GORE: An egotistical ass, who was once overheard by his Secret 
Service detail lecturing his only son that he needed to do better in 
school or he "would end up like these guys" --- pointing to the 
agents.* 
GEORGE W. & LAURA BUSH: The Secret Service loved him and Laura Bush. 
He was also the most physically "in shape" who had a very strict 
workout regimen. The Bushes made sure their entire administrative and 
household staff understood to respect and be considerate of the Secret 
Service. KARL ROVE was the one who was the most caring of the Secret 
Service in the administration.* 
*She was one of the nicest First Ladies, if not the nicest; she never 
had any harsh word to say about anyone.* 
BARACK & MICHELLE OBAMA: " Clinton all over again" - hates the 
military and looks down on the Secret Service. He is egotistical and 
cunning; looks you in the eye and appears to agree with you, but turns 
around and does the opposite---untrustworthy. He has temper tantrums.* 
She is a complete bitch, who hates anybody who is not black. Michelle Obama hates the military; and looks at the Secret Service as servants.*
