I'm sure you can get that info online. I will say that in the past (I can't speak for post Jerry Lewis MDA) the MDA was one organization that got the most bang for the buck. In other words, most of the money went directly to the cause with not as much administrative money coming out in comparison with other charity organizations.
George Bush, Ronald Reagan and other past Presidents have also noted this.
Not many people know that, but in 1977 – Jerry Lewis was Nominated for the Nobel Peace Prize, by US Representative Les Aspin.
Aspin noted that in 11 years, the MDA Jerry Lewis Labor Day Telethon had raised more than $95 million for the Muscular Dystrophy Association (he has of course, raised several orders of a magnitude more than that since the nomination).
While Jerry still has breath within him, I believe it would be appropriate for him to win a Nobel Peace Prize.
Hey, if the terrorist Yaser Arafat, the bloviator Al Gore and Barack Obama (who essentially won for nothing) can win that prize, why not Jerry Lewis? At least it would be more deserving...
