Yes, as did George Bush

When I was 19, in 1967, I looked into the National Guard.
Everybody knew the guard was the easiest way to avoid combat duty
in Viet Nam (was then, anyway). But I was told it was essentially
impossible to get into the guard. You had to know somebody.

It's also worth remembering the National Guard secretary who
said she didn't write the famous Dan Rather document did also
say "everything in that letter is essentially the truth, it's
just that I didn't write it."

Anybody who thinks George Bush's intermittant tenure in
the Texas National Guard was the same as Kennedy's duty
has a few cognitive wires crossed somewhere.
