There are two ways to storm the castle. One is to charge up the hill with torches and pitchfolks. That way fails. The other way is to persuade a majority of those holding the castle to change sides and open the gate. That method has often succeeded.
If we take over most of the Republican Party, plus a small part of the Democrats, as a combination, it will be a “third party” effort, but it will be a major party result. New thinking is needed.

I agree that this is feasible, though could it transpire in less than a generation's time?
In the interim, I'll stick with a Palin-led GOP.
