I believe you just did. Christie didnt “roll his eyes” when asked about Palin. He said “anything is possible” when asked if she can be elected. If you called him a coward based on what someone said he did, then that just makes you ignorant.
At best, Governor Christie ducked the question.
Rolling his eyes and saying “anything is possible” sends the politically correct message that a Palin presidency is a freak accident. But not speaking in a straightforward manner saves him the political risk of a backlash, because he knows his own support comes from Palin supporters.
Failing, on national television, to answer the most prominent question of current politics is not the action of a real leader.
Christie was unquestionably giving the politically correct, "Isn't insane that it's even a possibility?" response to the question about a Palin presidency. And that's exactly how the crowd and Fallon interpreted it.
That's fine, if that's his opinion. As I said, I like Christie very much, but he has a bit of that "nobody could possibly be as good for the job as me" personality. Same as Guiliani.
It's a good trait to have when you've got to beat down some unions or leftwing activists. But it might be limiting in the long term.
It sells for conservatives on the east coast, anyway - where people love to see some pretentious liberal douchebags smacked around now and then.
