My (re-edited and re-reconsidered) 2c (that probably makes it 1/4c - because it's an incomplete flip-flip-flop
I suggest that there is a very direct meaning in xkcd 1044 - with some speculation.
Every quote that Randall uses is quoted at http://en.wikiquote.org/wiki/Mitt_Romney
At the foot of that page are the following observations others have made on Romney:
"Well, I think you hit a reset button for the fall campaign. Everything changes. It’s almost like an Etch-A-Sketch. You can kind of shake it up and restart all over again.
Eric Fehrnstrom, CNN, quoted in Grier, Peter (21 March 2012), "Etch-A-Sketch: Can Mitt Romney shake off his aide's Mr. Potato Head gaffe?", Christian Science Monitor
You can't be a perfectly lubricated weather vane on the important issues of the day, whether it's Libya, whether it's the debt ceiling, whether it's the discussion around the Kasich bill in Ohio, where Gov. Romney has been missing in action in terms of showing any kind of leadership.
John Huntsman, CNN, quoted in Camia, Catalina (29 October 2011), "Huntsman slams Romney as a 'weather vane'", USA Today
That's one of the things that I like about him — because he’s been consistent since he changed his mind.
Christine O'Donnell, CNN, 2011-12-14, quoted in Lee, MJ (14 December 2011), "Christine O’Donnell: I like Mitt Romney's flip", Politico, retrieved on 2011-12-15"
Here's the way I (now) understand it ("This is the operative statement. The others are inoperative.").
“Nobody wants the prize more than young Charlie, but as his family is so poor that buying even one bar of chocolate is a treat, buying enough bars to find one of the five golden tickets is unlikely in the extreme.” – IMDB
Charlie Bucket was desperate to win the contest – in Charlie’s case it was his poverty that was the problem.
From Wikipedia: “Charlie... succumbs to temptation along with Grandpa Joe, as they stay behind in the Bubble Room and sample Fizzy Lifting Drinks. They begin floating skyward and are nearly sucked into a ceiling-mounted exhaust fan. To avoid this grisly fate, they burp repeatedly until they return to the ground. Wonka initially seems unaware of this incident... When Grandpa Joe returns to ask about Charlie's lifetime supply of chocolate, Wonka irritably reveals that Charlie had violated the contract by sampling the Fizzy Lifting Drinks, and thus forfeited his prize. Grandpa Joe vows to give Slugworth the gobstopper in revenge. Charlie, however, cannot bring himself to hurt Wonka and places the gobstopper on his desk...”
Charlie's misstep was his moral lapse of sampling the Fizzy Drink and he redeemed himself by doing the right thing and returning the gobstopper.
Mitt Romney’s problem, on the other hand is his wealth. With the exception of the snippet of the Medicare quote above, the other Romney quotes take positions that are safe for the independent voters who are critical to Romney’s presidential election chances.
The Medicare quote, however is a potentially dangerous one.
Mitt may have endangered his election chances with that one with too much frankness – unlike Charlie whose mistake was his moral lapse – Mitt, in the way of many politicians is endangered more, it seems by honesty than dishonesty - and politicians usually try to redeem such moments of rare frankness with obfuscation and doublespeak - a practice that many would say Romney seems to have made an "art" of.
So the irony is apparent - Mitt and Charlie are as alike as their quotes - the quest for lifetime chocolate was a contest of morality - whereas the quest for the White House sometimes seems to be reduced to a contest of vagueness and fudging.
