We already have this many “third parties”. Isn’t this enough? There’s a reason why they don’t win elections and another one will only make matters worse.http://en.wikipedia.org/wiki/Third_party_%28United_States%29
No third party has ever been made up of the Republican base. Unless you like the idea of being ignored in national elections every four years while the hand-selected candidate crashes and burns, it’s an idea well worth considering.
What is wrong with trying to make the party listen to US for a change? What is wrong with attempting to rebuild the Reagan coalition? Neither of things are possible inside the Romney/Rove/Boehner/McConnell Republican Party. And I suspect you know that.
