You will not have a successful primary challenge to the Speaker, unfortunately. He’s way too powerful. The way to oust him is to urge the Tea Party to endorse the Democrat for his seat in the general election. That is do-able. We sacrifice one seat for one election cycle, and we get rid of a corrupt Speaker. And I think the Tea Party should threaten to do the same thing to any successor who will not stand up and fight.
Oh, and support a convention, called by the state legislatures, to draft a term limits amendment to the constitution.
