‘ETHANOL IS A JOKE’…. It’s probably best to retire my ongoing count of John McCain’s Sunday show appearances. As of this morning, the Arizona Republican has been on 27 times in just two years, but I think folks get the point — Sunday show bookers continue to be obsessed with McCain, and they shouldn’t be.

What I found interesting this morning, though, is what the conservative senator said this morning, during his sixth appearance on “Face the Nation” over the last 24 months.

Sen. John McCain (R-Ariz.) sees an easy target in the drive to cut spending while leaving no “sacred cow” untouched.

“Ethanol is a joke,” he said Sunday on CBS’ “Face the Nation,” saying that programs promoting the corn-derived fuel are wasting millions.

That’s certainly a reasonable position to take, but it’s worth remembering that McCain went from being against ethanol (in 1999) to for it (in 2006) to against it again (in 2011), pulling off the hard-to-execute flip-flop-flip.

I can only assume McCain’s latest reversal will be perceived by his media champions as evidence that the “McCain of old” might yet make a comeback.
