AZ GOP No Tax Pledge

I get a kick out of the GOP, especially here in Arizona, they are highly entertaining.  Take their Anti-Tax Pledge for example, apparently it's only valid for state income taxes.   Remember the increased sales tax pushed by GOP Governor Jan Brewer?  Apparently, it doesn't count because it's a sales tax.  Now they've decided to limit 'homeowner rebates' which will cause local school districts to raise taxes via increased property taxes.  Again, it apparently doesn't count because it won't effect the state income tax rate. What a shell game and the GOP lemmings don't even see it, they're convinced that the GOP is looking out for them by keeping their state income taxes low.
