McCain Energy Policy Watch Day 418: Confused or Lying?

In a press conference today, though McCain betrayed that he's either deeply confused or deeply dishonest about his own proposal. Furthermore, since we're told that calling McCain "confused" is ageist, I guess we're left with dishonesty. McCain said:
QUESTION: The European Union has set mandatory targets on renewable energy. Is that something you would consider in a McCain administration? [...]As Gristmill pointed out, the cap part of cap and trade is a mandatory cap, even McCain's plan. McCain may not like the political framing of "mandatory," but saying that his plan does not include a mandatory cap is wrong on the facts.
MCCAIN: Sure. I believe in the cap-and-trade system, as you know. I would not at this time make those -- impose a mandatory cap at this time. But I do believe that we have to establish targets for reductions of greenhouse gas emissions over time, and I think those can be met.
So on the one level this story is a "gotcha!" John-McCain-ignorant-of-policy like so many others this year (Remember when Al Qaeda was in Iran? McCain does!). On another level, however, this exemplifies one of the most frustrating things about McCain's candidacy. He receives laudets for breaking with Bush on climate change (by acknowledging its existence-talk about a low bar!) but isn't held to any standard in his actions or policies!
McCain clearly doesn't prioritize climate change or energy issues, because if he did he would put forward a comphrehensive energy policy as Sen. Obama has done.
