Tickets to see Palin, announced at $185 on Jan. 16, eight days after Tucson, were slashed to half-price in early February. Then the speech was canceled altogether, with the organizers blaming “safety concerns resulting from an onslaught of negative feedback.” But when The Denver Post sought out the Glendale police chief, he reported there had been no threats or other causes for alarm. The real “negative feedback” may have been anemic ticket sales, particularly if they were to cover Palin’s standard $100,000 fee.

What may at long last be dawning on some Republican grandees is that a provocateur who puts her political adversaries in the cross hairs and then instructs her acolytes to “RELOAD” frightens most voters.
