It seems a big part of the main reason has been lost as the context has been lost.
Dan Quayle was able to avoid (potentially) going to Vietnam by getting preferential treatment through family connections to sign up for the National Guard. Unlike now when National Guard members are frequently used by the U.S military, at that time, the National Guard was a 'get out of Vietnam' card.
The John Fogerty/CCR song was written about such people (obviously not specifically Dan Quayle.)
Some folks are born made to wave the flag
Ooh, they're red, white and blue
And when the band plays "Hail to the Chief"
Ooh, they point the cannon at you
That was bad enough, but Quayle was also a hypocrite because he was a war hawk.
Also from Fortunate Son
Yeah-yeah, some folks inherit star-spangled eyes
Ooh, they send you down to war
And when you ask 'em, "How much should we give?"
Hoo, they only answer, "More, more, more, more"
From MacLean's Magazine
When news media charged that Quayle’s influential family had used its ties to help him avoid the draft during the Vietnam War, (Stuart) Spencer told Quayle that “it’ll pass.” But protesters still turn up at Quayle’s rallies in chicken suits with placards saying “Hell no, Quayle didn’t go.”

In his first press conference as a Vice Presidential nominee in 1988 neither he nor the collectively dimwitted media helped themselves. The media engaged in a 'feeding frenzy' on this question at the press conference and they did so in front of an Indiana audience who cheered Quayle, but Quayle also did himself no favors to the wider public with his dimwitted defense.
This is not from that press conference but it's a variation: I did not know in 1969 that I would be in this room today, I'll confess.
Essentially saying that had he known when he joined the National Guard and somebody else was possibly sent to fight and die in Vietnam in his place that only if he knew that he would been nominated for Vice President might he have done something different in 1969.
I do -- I do -- I do -- I do -- what any normal person would do at that age. You call home. You call home to mother and father and say, ``I'd like to get into the National Guard.''
-- Senator Dan Quayle, 8/19/88 (reported in Esquire, 8/92)
I got into the Guard fairly. There were no rules broken, to my knowledge... I, like many, many other Americans, had particular problems about the way the war was being fought. But yes, I supported my president and I supported the goal of fighting communism in Vietnam.
-- Vice President Dan Quayle (reported in High Times, 11/92)
In regards to his intelligence, this website has all his quotes:
https://www.cs.earlham.edu/~skylar/humor/Unix/quaylequotes.htmlThis is my favorite Quayleism:
I believe we are on an
irreversible trend toward more freedom and democracy - but that could change!
This has to be his oddest from the 1988 campaign:
I want to be Robin to Bush's Batman.
I had a brief discussion with a person who knew Dan Quayle in college and I told him the line that "Quayle was smarter than people gave him credit for, he just didn't think before speaking often enough" and he replied "No, Quayle is genuinely stupid."
