The only reason Carter ever got in office in the first place is because of President Nixon. Everyone wanted to put the national shame of Watergate behind us. Carter was a somewhat harmless threat since he had no real agenda. Hillary and Obama do have agendas. Looking back, Carter, the harmless threat ended up being the worst president we have ever had, and if the Soviets had taken advantage of it, it could have been the end for us. What ever we do, we can't stay away from the polls in November just to teach the Republican party a lesson about not being conservative enough.
Even if Fred goes and Mitt gets it, it we'll only prolong the inevitable, unless Mitt goes dead solid perfect on Reagan values, which I admit could happen, but I prefer not to deal with "could" when I have "will"...
Matters little to me though, I have positioned myself to weather the storm one way or the other. I vote for what is right.
