Nice strawman. Even if McCain is elected, he's not going to implement the FairTax or even reform the tax system. Hell he only came out with the same lame-old "keep Bush's tax cuts permanent" after getting heat from Romney.
The FairTax is a joke. Just implement a single 10% strict flat tax with no deductions or credits.
This is such a stupid argument anymore. Just be a sheep and let the governmant dictate how much of YOUR money they seize every week and keep voting Republican...
