Note that well over 80% of recall signatures were collected by people living outside the city.
Their affidavits (click link below) give their address--Texas, Michigan, California, Nevada, etc.
Many others were from the Denver area. Of the 61 affidavits, the only one that seemed to be from a resident of District 4 was the first one, by recall organizer Deborah Hendrix--TWO signatures of their 3,007 total.
