There are no obstacles to this today - except a vote in Congress and a signature. Why hasn't it happened yet?

Because people aren't stupid enough to want a huge Federal sales tax on top of every purchase of goods and services. There are only a few who want this to come to pass.

But your statement misses 2 very obvious facts:
1) The FairTax is not a "huge" Federal sales tax ... it's revenue neutral so raises the same funds as today's archaic tax system.
2) It's not "on top of" existing income taxes since those are removed by the FairTax bill and it's not "huge" in any event as most taxpayers presently paying income taxes will see their effective tax rate greatly reduced under the FairTax.
