Was 'pfft' the sound of you sticking your head up your ass? There was no parallel Presidential race going on during the California gubernatorial election, so your comparison means NOTHING.
What you are saying is absolutely nothing, it is intellectually vacuous arguing at best; that a primary battle is going to be divisive for a general election?
Really? Shocking! Tell us more, while you are at it, tell me why all those Dobsonites that are turning out are going to vote for the most outspoken proabort Republican in the Senate so he can have the honor of deciding on Judicial nominees?
Whether or not Snarlin is successful in hanging on in the primary, he has burned up his $10 million warchest and is finished in the general election. Clearly he needs to spend money to get votes, paying student $75 a day to "volunteer" while Toomey gets them for free. Why would a Kerry supporter vote to keep the GOP in the majority in the Senate? These are things that just don't pass the smell test. If I was a Dem there's no way I would want the GOP to control the Senate.
Your line of thinking is plagued with fear, and makes little sense when you get into it. I don't think you have thought it all out yet and ask you do.
