OV,

Let's say your view is 100% spot-on.  Oregon democrats found away to tax businesses with annual sales in Oregon above $25 million with a 2.5% rate with no, nada, nyet, 0 effect on Oregonians.  Hurray!  Yowza!  Raise that 2.5% another .05%!  How long do you think it will be before other states take notice and go for that "free" money also?  Do you think that will affect corporate national pricing strategy?  If so, it will only be a matter of time before Oregonians are "trickled" on.
