Here's the suspicion.
The Bush administration claims to be "making their own reality" are actually literally true. They are using a high tech "reality machine" or maybe a genie (and they've shrewdly wished for "infinite wishes.") The genie, maybe, was the real reason for invading Iraq (ooh it's all coming together now--djinn of mass destruction, no, WISHES of MASS DESTRUCTION!).
OK, you ask, why are things going so badly for them? I mean, if you are making your own reality, why wouldn't you make one where everyone loves Harriet Miers?
Two possible ways to answer this one:
First, the sci-fi/genie law of unexpected consequences/trickery. Arrogant closed-minded powermongers always dig their own graves. (or so claims the Twilight Zone).
OR (and this one I prefer)
Second, they've created their own reality but it's in a different dimension in which they (but not us) are now living. In their world, Iraq is a peaceful democracy, abortion is illegal for everyone, Katrina was a helpful "oil storm" which replenished the national energy reserves, and Bush eats Bill Clinton's liver for dinner every night (it regenerates). They've left replicants in their place in our dimension which are slowly corroding before our eyes.
