"Not constitutional to make sales tax deductable in some states and not in others - per the Equal Protection clause."

Agreed. State/local jurisdictions grab your money with a combination of income, property and sales tax. If your state uses property and sales tax only, then 100% of your tax burden is now deductible. If your state uses all three, then only the income and property tax is deductible.

The rule should be that ALL of these taxes are deductible for ALL residents of ALL states.

uh, I think it allows anyone to do so...it's just not worth it in states that have income tax burdens higher than sales tax. You get one or the other, right?
