I've just about had it
From the comments, at this post-
I have been voting for Republicans in every national election since I cast my first eligible vote for Gerald Ford against Jimmy Carter in 1976 (whose increasing bitterness and pettiness as he ages assures me I chose well in that election). I have been about as loyal as you can get and not actually be a Party insider and conventioneer. But that's over now. I've finally come to see that George W. is in fact like his father - that is to say, no conservative. Plus he forgot who brung him to the dance.
I've hung in there with him on the war because I think it is the height of folly to pretend we are not in a struggle for the very survival of western culture in the war which radical Islam has declared on us; and also because, having lived through the mortification and dishonor of surrender in Vietnam, I cannot bear to see our military once again betrayed by the cynical jackals, moral cowards and political opportunists. But I see that George W., just like his father before him, has used Republicans to get elected and then ignored most of us in attempting to curry favor with the Democrats and the left.
That is the Republican Disease - an elected Republican trying to make the Democrats and the chattering class like him. It cannot be done - nor should such a humiliating display even be attempted.
And now my President accuses me of bigotry and prejudice because I want the borders of my country soundly secured before even addressing the question of what to do with millions of illegal aliens. Well that just about rips the rug. Thank goodness I can still count on at least one of my Senators (Sessions) to place loyalty to principle ahead of loyalty to person. I'm tired of carrying W's water just to have it tossed on me.
Now as for 2008, I can't vote for any Democrat (except Joe Lieberman) - but neither do I care to support any of the mediocrities now jostling to see who can move to the center (and beyond) the quickest. Anything short of a Fred Thompson candidacy has no chance of getting my vote - and I'm not promising anything to him.
Libertarian, just to make a point? Could be. Could be.
I couldn't have said it any better. A pox on all of them.
