From this primary onwards, my strategy is to vote for any challenger to the GOP incumbent in any race. I urge fellow FReepers to do otherwise.
It's a real mystery to me how voters in conservative states like SC and AZ haven't been able to get rid of Graham and McCain in the primaries. I could understand not being able to do better in liberal states dominated by Democrats, but the only explanation for these guys' staying power in their states is the power of the GOP establishment and the inertia of incumbency.
