It has become obvious that a "Friend of Bill" (Clinton) is synonymous with "pedophile" or "human trafficker."
Private contractors were eager to sell services, in what one US envoy described in a Wikileaks-disclosed diplomatic cable as a "gold rush".
In email exchanges with top Clinton Foundation officials, a senior aide to Mrs Clinton, who was then-secretary of state, kept an eye out for those identified by the abbreviations "FOB" (friends of Bill Clinton) or "WJC VIPs" (William Jefferson Clinton VIPs).
"Need you to flag when people are friends of WJC," wrote Caitlin Klevorick, a senior State Department official who was vetting incoming offers of assistance coming through the Clinton Foundation.

Note particularly the "gold rush" comment.
Another possible meaning of "Trust Kansas" would be to "Trust the common people of
America." The center of the continental US is in Kansas, so "Middle America" could be a
synonym to Kansas. Just "thinking out loud."
