Well the 2012 Presidential Election is over, and you know what that mean. It's time for the race for the 2016 Elections to begin.
Unfortunately, I'm not kidding, they've already started. You don't need to act on it now, but when you watch what is going on in the news you should understand what they are doing and get ready for what's coming.
It was totally to Christie's benefit to do things that hurt Mitt Romney. If Romney had won, it would have made a run in 2016 more difficult for him. Just being considered a potential Presidential candidate in 2016 increases his influence, and he has four years to slim down.
When I look at the situation today, I see a situation that could easily carry him right into the Presidency. He could state very loudly that climate change exists, and his state has been a public victim of it. He can lambast his own party for not admitting it, and all of the sudden he looks like a revoloutionary figure.
That's not a bad thing, because we need to get over this denialism, but he can spin this easily into a presidential bid. It actually would have been to Obama's benefit at the polls to run more on climate change, but he didn't. Christie can effectively take the issue away from the next Democratic challenger, and then not actually do anything significant about it when he gets into office.
Not only that, he can point to being nice to Obama as evidence that unlike most Republicans he is capable of working with people across the aisle. That may not translate into real cooperation later, but it will sound good.
I think the main thing working against him at this point is simply his health, but right now he is a far more serious candidate than anybody else they have.
