Apparently there is an illuminated cross in the background of Huckabee's ad. Here is a screen shot from the youtube posting:
Peggy Noonan's most interesting point was: " I wound up thinking this: That guy is using the cross so I'll like him. That doesn't tell me what he thinks of Jesus, but it does tell me what he thinks of me. He thinks I'm dim. He thinks I will associate my savior with his candidacy. Bleh."
In some ways, she is judgmental: "He thinks I'm dim." Unless he told you that Peggy, we don't know that.
But she does point out the reality that we, the voting public, are viewed as means to the politicians end. So often we are no longer people to be served but means to their own political power. If they please us, it is only because it serves to strengthen, grow, or renew their own position.
I hope I'm not cynical.
If you want to read Noonan's column, do so here.
