Tom Friedman's Middle – Between A House And A Rock Place

Tom Friedman seems set to prove he’s worthy of Atrios’ honor. His latest column advocates a third party run for president by Mike Bloomberg, a man who doesn’t want to run and one with no chance of winning. Why? Because Tom believes in the tyranny of that same Buffet-Rule-hating fictional moderate middle that Bill Keller does. What a wanker.

And Tom, didn’t you or your editor catch yourselves at this line?

We need to weatherproof our American house ”” and fast ”” in order to ensure that America remains a rock of stability for the world.

Can you weatherproof a rock, more than it already is I mean? Can someone please drop a house, or even a rock, on this mixed metaphor?
