Survivors of Jared Loughner's shooting rampage in Tucson last year are calling on the presidential candidates to end gun violence.
"We demand a plan," said Bill Badger, Pat Maisch and Pam Simon, of Tucson, in a TV ad released Sunday.
Maisch, who was not injured, helped disarm Loughner.
The ad was paid for by Mayors Against Illegal Guns, which has more than 600 members. Phoenix Mayor Greg Stanton is the only Arizona mayor on the list.
