I reject your premise. The actions of a single issue lobbying group do not easily translate to political control among the two major parties. A young Democrat elected to the Senate will still be in office when you and I die, and he will never stray from the Democrat agenda.
The methodology works regardless of what issue triggers it. The Tea Party is *NOT* a majority. It is at best a Plurality, and most likely a minority. The only means by which a minority can control the outcome is by playing one side against they other, or have you ever heard of the "Gang of Eight"?
You get what you want by giving both sides reasons to fear you.
A young Democrat elected to the Senate will still be in office when you and I die, and he will never stray from the Democrat agenda.
That is a non sequitur. You are letting your FEAR speak rather than your mind. Grimes cannot win a second term. She is too far out there. Right now her only useful purpose is in helping us destroy a vicious traitor.
