It isn’t such a slam dunk. On the one hand Cruz is an easy pick, because he’d be oh so easy to beat in a national election. On the other hand I’d like to see some semblance of sanity return the the GOP, and picking Christie would be a nod in the direction of reality. Also, Christie would keep Cruz from even the possibility of becoming President. That issue looms large for me because flukey stuff can happen down the stretch and BAM! – you are looking at President Cruz.
As bad as Christie would be, the idea of President Cruz should make ever patriotic American break into a cold sweat.
