I don't see how Perry will sell it. It'll be demonized as a tax break for the 1% blah, blah.
The Flat Tax has the benefit (or liability?) of not being a brand new proposal, unlike 999, and not having the added sales tax component which has too many in an uproar.
On the downside, it won't have the sales tax so there's no capturing underground economy money. That part of 999 is appealing.
We'll see what Perry's version of a Flat Tax does on the low end and with deductions and whether this is income tax only reform or if it's deeper.
It's all academic though, Obama will win reelection.
That right there is a killer. Its time for everyone to pay their fair share.
