The Tucson Tea Party is having a big protest rally this Saturday at Tucson Electric Park. Billed as Tucson's Last Stand, it's a chance for conservatives and libertarians to express their displeasure with Democrats who are in power.

But there's one anti-tax message that might not be heard. Brandon Patrick, who is running the campaign against the Public Safety First initiative that city voters will decide on Nov. 3, says that he's having trouble connecting with Trent Humphries, the organizer of the event.

Patrick wants to have a chance to warn the crowd that Prop 200 will likely result in tax increases because the latest estimates show this unfunded mandate would cost the city nearly $64 million a year once it's fully implemented in five years.

UPDATE: Patrick tells The Range that Humphries did get back to him earlier today and let him know that neither pro-200 nor anti-200 representatives would be speaking at the event, but he was welcome to buy a booth.
